Description

FIELD OF TECHNOLOGY

This invention relates to the field of communication and specifically to a device, method, program and interface controlled by a touch screen for checking, controlling and interacting with devices.

BACKGROUND

Terminal emulators are a known method of emulating display terminals in some other information display system. A terminal emulator can, for example, be used to debug a computer’s operating system. To process error messages, some operating systems send them to the serial port of the computer.

To process error messages, a terminal (or a computer with a terminal emulator running) is connected to the serial port of the computer, which interprets the signal at the output of the serial port as a sequence of terminal commands. These commands allow you to display text on the terminal screen.

Users can use terminal emulators installed on personal computers (PCs), including a screen and input devices such as a mouse and keyboard, to test and manage devices. Information on the display and control information input from the input device by the user can be converted into serial signals and transmitted between the connected device and the terminal. The keyboard is used to transmit codes. Some keys send one or more codes immediately when pressed. Other keys, such as CTRL and SHIFT, do not send codes when pressed, but modify codes sent when other keys are pressed. The keyboard contains four arrow keys in four different directions. These keys convey control sequences. Upon receipt of such sequences by the terminal, the cursor will shift one character up, down, right or left.

Electronic devices with touch screens (such as smartphones, tablet computers, etc.) that allow users to enter information through the display are becoming increasingly popular along with the rapid development of programmable terminals. It may be convenient for users to use such devices controlled by a touch screen instead of a PC for checking and managing devices.

The touch screen of an electronic device replaces PC input devices such as a mouse and keyboard. The virtual keyboard of electronic devices does not necessarily have arrow buttons that can be used similarly to those arrows on the PC keyboard to change the cursor position. Therefore, one of the key problems in the development of terminal emulators for electronic devices with control via the touch screen is the development of a convenient way to change the cursor position.

Displaying the data stream offered by existing terminal emulators such as VT100 is not always convenient for interacting with the operating system of the connected device. For example, sometimes it is convenient to use other data formats such as hexadecimal, binary, etc., instead of displaying messages in the form of text. Existing terminal emulators also display both input and output data streams on one common screen, although it can sometimes be convenient to simultaneously generate displays of input and output data streams in different formats, for example, to display received data in text form and sent data in hex or binary format. It is also desirable to have a convenient way to enter data in formats other than text such as hexadecimal and binary. Thus, another important problem in the development of terminal emulators for electronic devices is the development of a convenient way to simultaneously display received and sent data, and the generation of sent data in real time in different formats different from those implemented in existing terminal emulators.

Touch screen electronic devices have different types of ports, such as Universal Serial Bus (USB) and wireless, such as Bluetooth and Wi-Fi. The user may need to work with one device on several different communication ports, or simultaneously work with several devices connected to different ports. Therefore, another important problem in the development of terminal emulators for electronic devices with touch screens is the development of a method that allows you to work with one device on several ports, or simultaneously work with multiple devices connected to different ports.

A device with a terminal emulator does not always have the required port for direct connection to a given device. For example, you may need to connect to the router via the command line interface, which may require the terminal to have a serial port or a USB port, while the terminal may only have a wireless communication port. Or there may be security, privacy, or other requirements that prevent direct access to the port of the device under study. The user may need to use an electronic device with a touch screen to establish a connection between such a terminal and a given device.

It may be convenient for the user to simultaneously use an electronic device with a touch screen to establish a direct connection between several communication ports, and to work with the terminal emulator on a different communication port. For example, you may need to establish a direct connection between USB and Bluetooth communication ports, and then connect the terminal emulator to the device via a Wi-Fi communication port, without breaking the connection between USB and Bluetooth ports. Therefore, another important task when developing terminal emulators for electronic devices with touch screens is to develop a method that allows you to simultaneously connect directly one communication port and emulate the terminal through another communication port.

The user may need to use different interfaces to communicate with different devices, such as a serial port (serial port, COM port, communication port), a virtual serial port (virtual serial port) or ports with protocols such as User Datagram Protocol, UDP) or Transmission Control Protocol (TCP). Therefore, another important task in the development of terminal emulators for electronic devices with touch screens is the development of a method that allows you to establish a connection with devices using various interfaces and protocols.

The user may need to use an electronic device to check, control and interact with the device through the transistor-transistor logic (TTL) interface to which other devices are also connected. This allows the user to use an electronic device with a touch screen to track messages that a given device exchanges with other devices via the TTL interface, and simultaneously send commands to the given device via the TTL interface, which can be useful, for example, when debugging the operation of a given device. Therefore, another important task is the development of a device that allows such simultaneous work with specified devices via the TTL interface.

The user may also need to exchange files with a given device using protocols such as Xmodem, Ymodem, etc. Therefore, another important task in the development of terminal emulators for electronic devices with touch displays is to develop a method that allows you to exchange files using different protocols.

Simultaneously with the TTL connection of the transceiver 40 through port 41 to the TTL port 44 of the microcontroller board 25, you can connect the transceiver 40 through port 41 to the device 4 via USB / TTL interface converter 12. For this, you may additionally require between the TTL port 44 of the microcontroller board 25 and TTL port 41 of the wireless transceiver 40 to include elements of electrical circuits 45 such as resistors. This allows you to use the device 4 to check, control and interact with the transceiver 40 via the TTL interface simultaneously with the microcontroller board 25 connected to the interface 41 of the device 40, making the electronic device with a touch screen a tool for diagnosing and debugging the interaction of devices 25 and 40 connected via the interface TTL. FIG. 7 shows the connection 13 of the wireless TTL transceiver 40 with an electronic device via a TTL / COM converter 46, for example, allowing the settings of the wireless transceiver 40 to be changed. The wireless TTL transceiver 40 and the wireless COM transceiver 42 can also establish a direct connection 13 to the electronic device 4 via TTL port 41 and COM port 43, respectively, as shown in FIG. 7. In FIG. 7 also shows the connection 13 of the router 47 and the electronic device 4 via the COM port of the router 48. In another example, shown in FIG. 7, the router 49 establishes a connection 13 by connecting the rj45 port 50 of the Cisco cable 51 to the rj45 port of the router command line interface 52.

In some embodiments of the invention, the developed terminal emulation method can be configured to work with various communication ports such as USB and wireless communication ports of an electronic device such as Bluetooth, Wi-Fi, etc. In FIG. 8, FIG. 10 shows a control block diagram of an electronic device 4. Examples of a user interface in accordance with an embodiment of the invention are shown in FIG. 9, FIG. 11-36. Touch screen settings allow the processor to convert user touch of the screen, including movement along the screen, into changes in the cursor position of the terminal emulator.

FIG. 8 shows a flowchart of a method for controlling an electronic device with a touch screen in accordance with one embodiment of the invention. The control of reading and writing data to ports 11, 16 and 20 of device 4 is performed by terminal emulators 53, 54 and 55, respectively, they also receive incoming commands from the touch screen 6 and send outgoing commands to the display screen of device 4, read and write memory 10, display user interface 7 of display 6. In FIG. Figure 8 shows the user interface elements 7 of display 6, including a terminal window 56, a separate terminal window 57 for incoming messages from the communication port, command line 58, virtual keyboard 59. Switching the interaction of terminal emulators 53-55 with user interface 7 is schematically shown by switches, switches 60- 65. Block 66 in FIG. 8 is designed to establish a direct connection between ports 11, 16, 20. The terminal emulator interfaces include writing to port 67 and reading from communication port 68, writing 69 and reading 70 command line data 58, writing 71 and reading 72 terminal window data 56, writing 73 data into a separate terminal window 57, reading 74 of the cursor position of the terminal window 56, writing 75 and reading 76 data from the direct connection unit 66.

In some embodiments of the invention, the display interface comprises a menu bar 77 shown in FIG. 9. Switching between terminal emulators shown in the block diagram of FIG. 8 by switches 60-65, can be performed, for example, by long pressing the button 78 of the menu bar 77, in which the button changes its appearance depending on which terminal is currently displayed, as shown in FIG. 9.

A block diagram of the emulators of terminal 53, 54, 55 for an electronic device with a touch screen 4 in accordance with one embodiment of the invention is shown in FIG. 10. The data 68 received from the port of the device 4 is placed in the memory block of the incoming messages 79. Data from the memory block of the incoming messages 79 is processed by the converter of incoming messages 80, which forms the resulting display of a separate window of the terminal 57 for incoming messages from the communication port stored in the block memory 81, or the display of the terminal window 56 stored in the memory block 82, for the selected data display format (text, hexadecimal, binary, etc.) and for the text data display format changes e of the terminal cursor shown in block diagram 83. In a text format for displaying data, the incoming message converter 80 also checks the incoming message memory 79 for the control sequences of the terminal: if a control sequence is found in the sequence of bytes stored in the memory block 79, this sequence is deleted from the memory unit 79, and an operation is performed for the terminal emulator in accordance with this control sequence. In the embodiment shown in FIG. 10, the terminal emulator has two cursor positions: one, called the user's cursor position, is set in accordance with the user's touches on the screen, including movements along the screen, and the second, called the terminal cursor position, is set in accordance with the terminal commands received from the connected device . In the embodiment shown in FIG. 10, both cursor positions are included for illustration in one block 83. Data from the memory block 82 is used to update the terminal window 56 displayed on the touch screen 6 of the electronic device 4. Pressing the keys of the virtual keyboard 59 changes the terminal window 56 or command line 58 located in bottom of the screen as shown in FIG. 11. The block of outgoing message processing 84 processes the events of the window of the terminal 56 and returns the window of the terminal 56 to its last state before entering from the keyboard, and sends the keypress data to the outgoing message converter 85. The block of outgoing message processing 86 processes the changes to the command line 58, returns command line 58 to its last state before entering from the keyboard, and sends data about keystrokes to buffer 87. When you press key 88, located under the terminal window 56 in the lower right corner of display 6 to the right of the command hydrochloric line 58, as shown in FIG. 11, this data is transmitted by block 89 further to the outgoing message converter 85, and the memory block 87 and the command line 58 are either cleared or not, depending on the processor settings. Processor settings are stored in memory 10. The settings user interface is opened by pressing the menu button 90 located in the menu bar 77 above the terminal window 56. Outgoing message converter 85 generates terminal commands and sends them to the outgoing message memory 91. Data is sent from the memory block 91 67 through the communication port 11, 16 or 20 and the connection 13, 17 or 21 to the port 15, 19 or 23 of the connected device 14, 18 or 22, respectively.

If the local echo mode 92 is enabled in the processor settings, the outgoing message converter 85 also sends a signal to the local echo block 93, which forms a display of the terminal window and updates the memory block 82 to display the echo of user commands in the terminal window 56. In some embodiments, according to According to the invention, in a textual data display format, the memory unit 82 stores terminal window data 56 in the form of a sequence of character strings of the same length W + 1, where W is the terminal window width in the number of characters. The row element index defines the x coordinate of the character position, and the row index determines the y coordinate of the character position. The value of the last character of each line is set equal to the newline character ‘\ n’. When receiving instructions from the outgoing message converter 85 to write a new character to the terminal window 56, the local echo block 93 updates the position of the user cursor to the current position of the terminal cursor, uses the position of the terminal cursor, determines the line index and character index of this line, and changes its value to received from the outgoing message converter 85. After that, the value of the position of the user cursor and the position of the cursor of the terminal is updated. Upon receipt of a newline character ‘\ n’ from the converter of outgoing messages 85, the local echo block 93 does not record it in the memory block 82, but updates the value of the terminal cursor position and the position of the user cursor in accordance with the selected method of processing the end of line character during signal transmission. In some embodiments of the invention, the window area of the terminal 56 is configured to display character strings. Upon request, the terminal window 56 processes the lines from the memory block 82 and displays them on the screen so that each character of the end of the line ‘\ n’ begins a new line. An example of a current implementation of a terminal window is Edit Text, a subclass of the Android TextView class.

In some embodiments of the invention, the processor settings comprise a user cursor option. If the local echo 92 is turned on or the local echo 92 is turned off but the user cursor option is turned on, then the touch processing unit 94 processes screen touches including movements along the surface of the terminal window 56, sends terminal commands to the outgoing message memory 91 and updates the position of the user cursor. In case of loss of focus by the window of the terminal 56 or receiving focus, the new position of the user cursor is compared with the last position. If the position of the user cursor has changed, the terminal command sequence corresponding to this change is sent to the memory block of the outgoing signal 91. In some embodiments according to the invention, the terminal window occupies only part of the screen window area of the terminal. If the cursor is dragged outside the borders of the terminal window or a click is made on the screen window area of the terminal outside the borders of the terminal window, the cursor position is limited by the borders of the terminal window.

In case 95, if both the local echo and the user cursor option are turned off, the touch processing unit 94 does not process touches on the terminal window 56 and does not update the position of the user cursor. If the local echo mode 92 is turned on, then the touch processing unit 94 applies changes in the position of the user cursor to the position of the terminal cursor, otherwise the position of the terminal cursor changes only when receiving terminal commands from the connected device. The user cursor position is used by the touch processing unit 94 to generate outgoing messages 91 of the terminal commands sent to the memory unit that correspond to pressing the arrow keys, and the terminal cursor position is used to determine the current cursor position, where either the character received from the connected device or the local echo should be placed display the character entered by the user from the virtual keyboard 59. Pressing the basket button 95 in the menu bar 77 will clear the memory blocks 81, 82 and 87. Pressing the button Information Menu 96 opens the application information and records section of the journal transmitted and received signals. A single press of the menu button 78 starts the connection / disconnection procedure of the device.

When no devices are connected and no program settings are selected, terminal window 56 is inactive. After connecting the device and selecting user settings 90, the terminal window 56 becomes active, and clicking on the terminal window 56 or command line 58 opens the virtual keyboard 59, as shown in FIG. 13. When opening the virtual keyboard 59, the terminal window 56 changes its size to the area above the keyboard. As the screen rotates from portrait to landscape, the terminal 56 and virtual keyboard 59 change orientation, as shown in FIG. 14. When rotated from landscape to book mode, the terminal returns to the state shown in FIG. 13. If the automatic scaling option is turned on in the application settings, during rotation, the font size of the text 97 of the terminal window 56 automatically changes 98 so that the width of the terminal window remains the same in the number of characters and equal to the value defined in the application settings, and the terminal window fills the entire screen width 99 of the device as shown in FIG. 15. If automatic scaling is disabled, the font size remains equal to the value defined in the processor settings, as shown in FIG. 16. Moreover, if during rotation the new width of the screen 100 is less than the length of the line of text 101 in the terminal window, then part of the text outside the right border of the terminal window will be cut off.

In some embodiments of the invention, a button 102 is added to the left of the command line 58. A single click on the button 102 switches the outgoing message processing unit 86 and the command line 58 between different display formats (text, hexadecimal, binary, etc.) so that the button 102 displays the designation of the corresponding format (AB, 0x, 0b, etc.) as shown in FIG. 17. In some embodiments of the invention, another button 103 is added in the lower right corner of the terminal window 56. Pressing the button 103 switches the outgoing message processing unit 84 and the terminal window 56 between different data display formats (text, hexadecimal, binary, etc.). ) so that the button 103 displays the designation of the corresponding format (AB, 0x, 0b, etc.), as also shown in FIG. 17.

In some embodiments of the invention, non-text data display formats (hexadecimal, binarone, etc.) use an intelligent data input / delete method. When you enter the first character of a new number, a prefix for the selected display format is added at the beginning of the number (for example, the prefix 0x for hexadecimal format 104, the prefix 0b for binary format 105). If the input is carried out in the terminal window 56, then after entering the last character of the number in non-text format, the corresponding value is sent by the outgoing message converter 85 to the outgoing message memory 91. When the last character of the number in the non-text format is deleted in the terminal window, the outgoing message converter 85 sends the code 0x08 to block of memory of outgoing messages 91. When deleting other characters of numbers in non-text formats, the converter of outgoing messages 85 does not generate any signals for memory block 91. This The method allows you to enter data in such formats as hexadecimal and binary in real time, as if they were entered and deleted with a single keystroke. The same approach can be used for other data formats, for example, for octal format, etc. When deleting the first character of a number in non-text format, the prefix is also automatically deleted.

In some embodiments, according to the invention, in non-text presentation formats when the "." Key is pressed 106 of the virtual keyboard 59 after completing the input of the last number 107 in the terminal window 56 or the number 108 on the command line 58, the next number entered will be the number of repetitions of the same number sent one after another. If you enter 108 on the command line 58, then after pressing the "." 106, the format designation on button 102 to the left of the command line will turn green. After entering the number, the format designation on the button 102 will turn black. When the button 88 is pressed, the corresponding number of repetitions of the code 108 will be sent to the connected device. When you erase the last character of a number in a non-text format on the command line 58, starting with a prefix, starting with a character, the symbol on the button 102 will turn green, indicating that the number being edited is the number of consecutive repetitions of the number before the prefix.

If you enter in the terminal window 56, then when you press the "." 106 of the virtual keyboard 59, the format designation displayed on the button 103 in the lower right part of the window of the terminal 56 will turn green. After completing the input of the number, it will turn blue, and the next number entered will be the value of the new code sent. When you enter the first character of a number in non-text format after pressing the "." 106, a prefix starting with a “-” is displayed (for example, the prefix “-0x” 109 is displayed for the number 107 in hexadecimal format), indicating that the number entered represents the number of times the code is repeated. When you enter the last character of the number, the corresponding number of code repeats will be sequentially sent by the outgoing message converter 85 to the outgoing message memory 91.

If the last character of the number is deleted in a non-text format, then if the number starts with a prefix starting with a "-" character (for example, the prefix "-0x" for a hexadecimal number), then the next number of repetitions of the code "0x08" will be sent by the outgoing message converter to the memory block of outgoing messages 91. Thus, in order to send the code 0xab N + 1 times, you must first press "a" and "b", then press the "." 106 and enter the number N in the appropriate presentation format. For example, for a hexadecimal representation format, this allows you to send up to 256 consecutive repetitions of the same code. If local echo 92 is turned on, then when sending sequences from the command line, the local echo block 93 converts them to the view installed in the terminal window 56.

When the last character of a number in a non-text format beginning with a prefix starting with a character is deleted in the terminal window 56, the symbol on the button 103 will turn green, indicating that the number being edited is the number of consecutive repetitions of the number before the prefix. If you enter the last character of the number again, a new number of repetitions of the code will be sent (for example, code 107 for hexadecimal format) and the symbol on the button 103 will turn blue. Otherwise, when you erase the first character of a number starting with a prefix starting with a prefix, the prefix will also be automatically deleted, and the color of the notation on the button 103 will turn blue.

In some implementations according to this invention, sending the 0x08 code when the erase key is pressed can be enabled or disabled in the processor settings.

In some implementations according to the invention, for convenient access to the set of control sequences, a button 110 is added in the lower left corner of the terminal window 56. When pressed, the control sequence input mode is activated, in which outgoing message processing units 84 and 86 transform the keystrokes of the virtual keyboard 59 into appropriate escape sequences. For example, when you press button A 111, the outgoing message processing unit 84 converts it to the control sequence CTRL-A equal to 0x01, when you press button B 112, the processing unit for outgoing messages converts it to the control sequence CTRL-B equal to 0x02, etc.

In some implementations according to the invention, the local echo unit 93 and the incoming message converter 80 can automatically complete the input of numbers entered in non-text formats in the terminal window. According to this method, if the local echo is turned on, by pressing the send message button 88, before displaying the command line message 58 in the terminal window 56, if the last number in the non-text format is not completed 113, the number is automatically completed by filling in the zeros remaining for the input or by deleting a number depending on the selected settings. When the converter receives incoming messages 80 messages from the connected device, the input of the number will also be automatically completed by filling in the remaining characters for entering zeros or deleting the number, depending on the selected settings.

In some implementations according to the invention, a button 114 and a list of elements 115 are added to the bottom of the terminal window. If the device is connected and command line 58 is not empty, pressing button 114 opens a dialog 116, as shown in FIG. 18. When you click button 117 to list 115, adding a new item. If the text field 118 is not empty, then the name of the new element will be set in accordance with its value, otherwise it will be set in accordance with the serial number of the new element in the list 115. When you click on the button 119, the dialog 116 closes without any additional actions. When you click on a list item 115, for example 120, its value 121 is displayed on the command line 58 and command line 58 switches to the data format in which the value 121 (text, hexadecimal, binary, etc.) was saved, and the button 103 will display the corresponding designation (AB, 0x, 0b, etc.) as shown in FIG. 17. By long pressing the same element 120, a dialog 122 will appear, as shown in FIG. 19. Pressing the button 123 saves the new value of the list item 115. Pressing the button 124 removes the list item 115. Pressing the button 125 closes the dialog without further action.

In some embodiments of the invention, a method is used to show / hide individual buttons by long pressing other buttons. For example, in accordance with the implementation variant shown in FIG. 20-22, a long press on the button 88 shows / hides the button 114 and the list 115, as shown in FIG. 20 and FIG. 22, and a long press on the button 102 shows or hides the buttons 110 and 103, as shown in FIG. 21 and FIG. 22.

In some embodiments of the invention, a separate terminal window 57 for received messages is added, as shown in FIG. 23. The windows of the terminals 56 and 57 have separate memory blocks, the memory block 81 for the terminal window 57 is filled with the incoming message converter 80, and the memory block 82 for the terminal window 56 is filled with the local echo block 93. For the same data display in both windows, the buttons 103, 110 114 and the list 115 located at the bottom of the window 56 for non-windowed embodiments 57 are moved to a line dividing the windows of the terminals 56 and 57, as shown in FIG. 23. The position of the user cursor, updated by processing touches to the screen including movements along the screen, now affects only the operation of the local echo block 93 for the terminal window 56, and the position of the terminal cursor is now used only by the incoming message converter 80 for the terminal window 57. Pressing the button 103 switches the display of the data of the terminal window 56 between different presentation formats (text, hexadecimal, binary, etc.). Pressing the button 102 switches the presentation format of the command line data 58. For embodiments with the terminal window 57, this pressing additionally switches the display of the terminal window 57 for the received signal between different presentation formats (text, hexadecimal, binary, etc.). For a text format, both terminal windows are converted using the method shown in FIG. 15 and FIG. 16. FIG. 24 shows a screen layout application with two windows for landscape orientation. In some embodiments of the invention, two separate screens for received and sent messages can be used for messaging.

In some embodiments according to the invention, a switch is made between a screen layout with one common and two separate terminal windows for received and sent messages, as shown in a block diagram with switches 126 and 127. For a terminal with terminal window 57, a switch 126 connects an incoming message converter 80 with a memory block 81 for the terminal window 57, and the switch 127 is open so that the position of the terminal cursor is used only by the incoming message converter 80 for the terminal window 57. For t rminala terminal box 57 without the switch 126 connects the transducer 80 incoming messages to the block memory 82 for the terminal box 56, and the switch 127 is closed so that the position of the user and the cursor and the position of the cursor used by the terminal local echo block 93 via block 83.

In some embodiments, according to the invention, for a terminal with a terminal window 57 in text format, upon receipt of a terminal command from the memory unit 79 corresponding to pressing the arrow button, the incoming message converter 80 updates the position of the terminal cursor. If the command to write a new character to the terminal window 57 is received, the input signal converter 80 uses the current value of the terminal cursor position to update the terminal window 57, and then updates the terminal cursor position.

In some embodiments according to the invention, for a terminal with a terminal window 57, the memory unit 81 stores the data of the window of the terminal 57 in a text representation as a sequence of lines of the same length W + 1, where W is the width of the terminal window in the number of characters. The row element index gives the x coordinate of the character position, and the row index gives the y coordinate of the character position. The value of the last character of each line is equal to the value of the newline character ‘\ n’. Upon receipt of a terminal command corresponding to the arrow button from the incoming message memory 79, the inbound message converter 80 updates the terminal cursor position. Upon receipt of the instruction for writing a new character to the terminal window 57, the incoming message converter 80, using the position of the terminal cursor, determines the line index and the line character index, and changes its value to the value obtained from the memory unit 79. Then, the position of the terminal cursor is updated. Upon receipt of a character sequence selected from the processor settings as a new line sequence from the memory unit 79, the incoming message converter 80 does not record this sequence in the memory unit 81, but updates the position of the terminal cursor. In some embodiments of the invention, the window area of terminal 57 is configured to display character strings. Upon request, the terminal window 57 processes the lines from the memory block 81 and displays them on the screen, each symbol ‘\ n’ begins a new line. An example of such an implementation of a terminal window area is EditText, a subclass of Android's Text View class. In some embodiments, according to the invention, for a terminal without a window of the terminal 57, in a textual representation, upon receipt of a terminal command corresponding to the arrow button from the incoming message block 79, the incoming message converter 80 updates the position of the terminal cursor and the position of the user cursor. Upon receipt of an instruction to write a new character from the memory unit of the incoming messages 79 to the terminal window 57, the incoming message converter 80, using the terminal cursor position, updates the terminal window 57 and then updates the terminal cursor position.

In some embodiments of the invention for a terminal without a terminal window 57 in text format, the memory unit 82 stores window data of the terminal 56 in the form of a sequence of character strings of the same length W + 1, where W is the width of the terminal window in the number of characters. The index of the line element determines the x coordinate of the character, and the line index determines the coordinate of the character. The last character of each line is set to ‘\ n’. Upon receipt of a terminal command corresponding to the arrow button from the memory block of incoming messages 79, the incoming message converter 80 updates the position of the terminal cursor and the position of the user cursor. Upon receipt of instructions from the memory unit of incoming messages 79 for recording a new character in the terminal window 56, the incoming message converter 80 updates the position of the user cursor to the current value of the position of the terminal cursor, using the position of the terminal cursor, determines the line index and the line character index and changes its value to the value received from the memory block of the incoming messages 79. After that, the position of the user cursor and the position of the terminal cursor are updated. Upon receipt of a symbol sequence selected from the memory unit 79 as the new line sequence in the application settings, the incoming message converter 80 does not record this sequence in the memory block 82, but updates the position of the terminal cursor and the position of the user cursor. In some embodiments of the invention, the window area of the terminal 56 is configured to display character strings. Upon request, window 56 processes the lines from memory block 82 and displays them on the screen, each ‘\ n’ character starts a new line. An example of such an implementation of a terminal window is EditText, a subclass of the Android TextView class.

When button 147 is pressed, dialog 142 closes without creating an access point. To connect a given device as a client, you must connect to the access point of the electronic device 4 and create an outgoing connection on it, for example, using the TCP protocol. To close the Wi-Fi connection, press the button 78 again.

In some embodiments of the invention, communication with a given device can be established using Wi-Fi Direct protocols that allow Wi-Fi devices to communicate without routers and access points. In this case, the processor can be configured so that both devices supporting Wi-Fi Direct protocols and devices without support for these protocols can be connected to it.

In some embodiments of the invention, various protocols are used to transmit and receive files, such as Xmodem, Ymodem, etc., or protocols are not used. In the case of transferring a file instead of writing data to the outgoing message memory unit 91 from the signal conversion unit 85, the modem 148 writes to the outgoing message memory unit 91 data from the local file 149 and the responses sent to the connected device. In the case of receiving a file instead of writing data to the incoming message converter 80, the received packets and responses from the connected device are received by the modem 148, and the received information is written to the local file 150. To transfer files to the menu panel 77, the button 151 is added. When the button 151 is pressed over the terminal window 56, a file transfer dialog 152 is opened, as shown in FIG. 30. Pressing the button 153 in the upper left corner of the dialogue 152 allows you to select the transfer protocol 154. The button 155 in the lower left corner of the dialogue 152 allows you to select the transfer direction 156. File transfer is activated by pressing the button 157 in the lower right corner of the dialogue. Another click on the button interrupts the file transfer. At the beginning of the transfer, a line 158 appears under the dialog with information about the transfer status, the number and percentage of transmitted bytes and the average transfer rate. A download bar 159 is also displayed to visually display the percentage of transmitted data. When transferring the file, pressing button 157 displays a list of files 160 located in the local directory, for example, / UDevTerm / Sent, as shown in FIG. 31. Clicking on a list item, for example, 161, selects the corresponding file for transfer. If file acquisition is selected, pressing the button 157 depending on the selected protocol may display a dialog 162 for selecting the name of the file to be saved, as shown in FIG. 32. For example, this option can be used when receiving a file without a protocol and using the Xmodem protocol. Line 163 contains the name of the file to be written to, located in the local directory, for example, in / UDevTerm / Save. When button 164 is pressed, the application will try to create the corresponding file. When button 165 is pressed, file acceptance will be canceled. If the file already exists, pressing button 164 for any protocol displays a dialog 166 asking whether to overwrite the file, as shown in FIG. 33. When the button 167 is pressed, the file information will be deleted. Pressing 168 will cancel the file. The following sequence of actions can be used to send / receive a file. First, a button 151 is pressed to open a file transfer dialog 152. Secondly, the button 153 is pressed to select the desired protocol 154. Thirdly, the button 155 is pressed to select the transmission direction 156, the button 157 is pressed to start the transfer. Fourthly, a file name is selected to save data at reception, if required. Fifth, the application opens on the connected device and a connection is established with the required settings. The data transfer protocol is selected and transmission begins. Sixthly, at the end of the transmission, the results of the transmission are checked.

During transmission, the dialog 152 can be hidden by pressing the menu button 151 of the panel 77. The button 151 changes to 170 during transmission and 171 during reception to inform the user about the transmission status if the dialogue 152 is hidden, as shown in FIG. 34. Button 151 returns to its original form 169 at the end of the transfer.

In some embodiments of the invention, the processor is configured to perform various mathematical calculations that may be useful when working with various data formats such as text, hexadecimal, and binary. To access these calculations, a button 172 has been added to menu bar 77, as shown in FIG. 35. When you click on it, window 173. opens. This window may contain various mathematical tools, for example, it may contain fields 174, 175, 176 for entering numbers in decimal, hexadecimal and binary representations, respectively. If one of the fields is filled, the other two fields are automatically updated. You can also add a field 177 for entering sequences of numbers in hexadecimal format for calculating CRC values, for example, for the Xmodem protocol. A window can be configured to paste copied data into it. After pressing button 178, the CRC value in hexadecimal format is displayed in field 179.

In some implementations according to the invention, the processor is configured to establish several simultaneous connections so that each of them is processed by an independent terminal emulator. For example, in accordance with an embodiment of the invention, a block diagram of which is shown in FIG. 8, the processor is configured to simultaneously establish connections 13, 17 and 21 through ports 11, 16 and 20 with devices 14, 18 and 22, respectively (for example, one connection via a USB port, one via a virtual Bluetooth serial port and one connection via Wi-Fi port with TCP protocol). The terminal emulators 54, 55, and 56 operate independently so that one of them displays information and receives information from the user, while the other operates in the background. Switching between the terminals is carried out by long pressing the button 79 of the menu bar 78.

In some embodiments of the invention, the processor is configured to simultaneously transfer files independently across multiple connections, as shown in the block diagram of the embodiment of FIG. 8., where the modems 147 of the terminals 54, 55 and 56 perform simultaneous independent file transfer via ports 11, 16 and 20 of the electronic device 4, respectively.

In some embodiments of the invention, as shown in the block diagram of FIG. 10, the switch 180 corresponds to the method of attaching an incoming message memory block 79 either to an incoming message converter 80 of the terminal emulator, or to a modem 148 for receiving files and responses from a connected device in case of file exchange, or to a connection control unit 66 for direct connection of ports between connected devices. The switch 181 corresponds to the method of attaching the outgoing message memory unit 91 to either the outgoing signal converter 85 of the terminal emulator, or to the modem 148 for transferring files and responses to the connected device in case of file exchange, or to the connection control unit 66 for direct connection of ports between connected devices. The switch 182 corresponds to the method of attaching the touch processing unit 94 to the outgoing message memory unit 91 to turn on the unit when using the terminal emulator or turn off the unit when transferring files or direct communication between the connected ports.

The specified device does not always have the required port type for direct connection to the terminal. For example, you may need to connect to a router through a command line interface that requires the terminal to have a serial or USB port, while the terminal can only have a wireless port. Or there may be security requirements or other requirements that do not allow direct access to the port of a given device. In some embodiments of the invention, the processor is configured to create a direct, controlled connection between several connected devices, for example, between devices 14 and 18, as shown in the block diagram of FIG. 8. In this method, the memory blocks of the outgoing messages 91 and the memory blocks of the incoming messages 79 of the terminal emulators 53 and 54 are connected via the connection control unit 66, as shown in FIG. 8. Connection control unit 66 can be used for various purposes such as monitoring, filtering, security, etc. To connect ports 11 and 16, a long press on the menu button 78 is required, after which the button changes its appearance, for example, to 183, 184 and finally to image 185, indicating a direct connection of ports. At the same time, a dialog 186 is displayed on top of the terminal window 56 to establish a direct connection between the ports, as shown in FIG. 36. Buttons 187, 188, 189 of dialogue 186 correspond to connections 11, 16 and 20. If the connection is established, then the corresponding button of 187, 188 and 189 is yellow. Otherwise, the button is red. If the connection is established and the corresponding button is yellow, pressing this button, for example 187, selects the appropriate port to establish a direct connection, and the color of the button 187 turns green. When you press the second button from 187, 188 and 189, for example, 188, for the port for which the connection is established, the button color turns green, and the connection of outgoing message memory blocks 91 and incoming message memory blocks 79 of terminal emulators 53 and 54 is established, after whereby the menu button 78 also turns green, indicating that the connection of ports 11 and 16 is established. If you click on one of the buttons 187 and 188 again, then the memory blocks of outgoing messages 91 and incoming messages 79 of terminals 53 and 54 are disconnected from connections 75 and 76 with block 66, and are connected back to blocks 85, 94 and 80, respectively, and the color buttons 78 turns yellow, indicating that the direct connection between ports 11 and 16 is disabled.

It may be convenient for the user to simultaneously use an electronic device with a touch screen to establish a direct connection between several communication ports, and to work with the terminal emulator on a different communication port. For example, you may need to establish a direct connection between USB and Bluetooth communication ports, and then connect the terminal emulator to the device via a Wi-Fi communication port, without breaking the connection between USB and Bluetooth ports. In some embodiments of the invention, when establishing a direct connection between, for example, ports 11 and 16, switches 60-65 connect the interfaces 7 and 8 to the emulator 55, allowing the terminal 55 to be used with port 20 without breaking the direct connection between ports 11 and 16. As long as the direct connection between ports 11 and 16 is turned on, a long press on the button 78 of the menu bar 77 hides and displays a dialog 186, allowing you to work with the terminal 55 interface. At the same time, the remaining interface functions for the terminal emulator 55 described above, work They are the same as without a direct connection between ports 11 and 16. When closing a direct connection between ports 11 and 16, the switches 60-65 are disconnected from the emulator 55, and a long press on the button 78, as before, switches interfaces 7 and 8 between various terminal emulators and direct connection between ports.

Otherwise, the connection is not established 203 and the configuration process ends. Upon receipt of an incoming connection, the server receives it 204. In the case of an error 205, the connection is not established, and the configuration process ends. Otherwise, if the connection is established 206, in the next step 207, the server tries to receive inbound and outbound socket data streams. In case of error 208, the connection is interrupted and the configuration process ends. Otherwise, the connection is considered established 209 and the configuration process ends.

FIG. 40 shows a functional diagram with steps for configuring a virtual serial port for a client, in accordance with one embodiment of the invention. In step 210, a serial connection socket is created. If creation was successful 211, an attempt is made to connect to the specified device. Otherwise, the connection is not established 212 and the configuration process ends. The process ends even then, if an error 214 occurred while trying to connect 213. If the connection 215 is established, then in the next step 216 the client tries to receive the incoming and outgoing socket streams. In case of error 217, the connection is closed and the configuration process ends. Otherwise, the connection is considered as established 218 and the configuration process ends.

FIG. 41 shows a functional diagram with steps for configuring a TCP port for an access point, in accordance with one embodiment of the invention. In step 219, a server socket for the Transmission Control Protocol (TCP) is created. If the socket was successfully created 220, a cycle begins to wait for incoming connections 221. Otherwise, the connection is not established 222 and the configuration process ends. Upon receipt of an incoming connection, the server accepts it 223.

FIG. 42 shows a functional diagram with steps for configuring a TCP port for a client, in accordance with one embodiment of the invention. At step 229, a socket is created for the Transmission Control Protocol (TCP). If the creation was successful 230, an attempt is made to connect to the specified device. Otherwise, the connection is not established 231 and the configuration process ends. The process ends even then, if an error 233 occurred while trying to connect 232. If the connection 234 is established, then in the next step 235, the client tries to receive the incoming and outgoing socket streams. In case of error 236, the connection is closed and the configuration process ends. Otherwise, the connection is considered as authorized 237 and the configuration process ends.

FIG. 43 shows a functional diagram with steps for transferring files using protocols such as Xmodem and Ymodem, in accordance with one embodiment of the invention. At step 238, incoming messages are expected to be received. Loop 238 is executed until no messages are received or received messages 239 do not contain the values 0x43 and 0x15. If a 240 0x15 message is received, then the protocol for 8 bit values of the Cyclic Redundancy Check (CRC) 241 is used, and a 242 0x06 0x15 response is sent to the connected device. If a 243 0x43 message is received, then a protocol with 16 bit CRC values of 244 is used, and a 245 0x06 0x43 response is sent to the connected device. After step 242 or step 245, step 246 is executed in the loop to read data from the file. Until the file is finished reading, step 247 is performed to transmit packets to the connected device containing the header, data from the file and CRC value for error detection. After each packet is sent, a 248 response is expected from the connected device. Upon receipt of a 249 0x06 response from the connected device, the previous transmission is considered successful and the execution of step 246 is repeated. Upon receipt of a 250 0x15 response from the connected device, the previous transmission is considered unsuccessful and the packet is sent again 247. Upon receipt of 251 several consecutive 0x18 bytes and the same number of consecutive byte 0x08 (for example, eight bytes 0x18 and eight bytes 0x08) from the connected device, the same sequence is sent to 252 connected devices and transmission is interrupted. The same sequence 252 is sent to the connected device if the user decides to abort transmission 253. If the file is finished reading, the connected device sends 254 message 0x04, and the transfer ends.

FIG. 44 shows a functional diagram with steps for receiving files using protocols such as Xmodem and Ymodem, in accordance with one embodiment of the invention. At the first step, a timer 255 is started so that at equal intervals the connected device is sent 256 code 0x15 if 8-bit CRC values are used, or code 0x43 if 257 uses 16 bit CRC values. During run time 255, the port of the electronic device is checked for responses 258 from the connected device. The loop continues until a response of 0x06 0x15 or 0x06 0x43 is received. Upon receipt of a 259 response 0x06 0x15 or upon receipt of a 260 response 0x06 0x43, a cycle starts in step 261 to read data received from the connected device. When 262 0x04 messages are received from the connected device, the file reception is considered completed and the process ends after sending 263 0x06 response to the connected device. Upon receipt of 264 multiple consecutive bytes 0x18 and the same number of consecutive bytes 0x08 (for example, eight bytes 0x18 and eight bytes 0x08) from the connected device, the same sequence is sent to 265 the connected device and the file is stopped. Otherwise, the packet header is received, the received data and CRC value 266. Read 267 continues until received 268 known number of bytes of the packet. After that, the CRC value of 269 is calculated for the received data and 270 is compared with the obtained value. If these two values coincide, then 271 code 0x06 is sent to the connected device and then step 261 is executed. Otherwise, if the CRC values do not match, 272 code 0x15 is sent to the connected device.

In some embodiments of the invention, as shown in FIG. 45, the position of the cursor of the user 273, 274, 275 of the terminal emulator, when you click on the screen 276, 277, 278 including movements in directions 279, 280, 281, along the surface of the screen along the paths 282, 283, 284 at each moment of time corresponds to a point in which is currently pressed on the screen (pressing the screen 276 with a movement in the direction 279 corresponds to the position of the user cursor 273, pressing the screen 277 with a movement in the direction 280 corresponds to the position of the cursor of the user 274, pressing the screen 278 with the movement in the direction 281 corresponds the user cursor location 275), and when the point on the screen at which the screen is currently being pressed is changed, the terminal emulator generates terminal commands sent by device 4 to specified devices connected to device ports 4 corresponding to the terminal cursor moving to a point, in which the screen is currently being pressed (when the screen is pressed from point 276 to point 277, the terminal emulator generates terminal commands corresponding to the movement of the user cursor from position 273 to position 274, when the screen is pressed from point 277 to point 278, the terminal emulator generates terminal commands corresponding to moving the user cursor from position 274 to position 275).

In some embodiments of the invention, the virtual keyboard 59 and the touch processing unit 94 simultaneously input text and touch processing on either the terminal window 56 if the terminal window is active or the command line 58 if the command line is active. The terminal window 56 becomes active when you click on it and becomes inactive when you click on the command line 58. The command line 58 becomes active when you click on it and becomes inactive when you click on the terminal window 56. If the terminal window 56 was active, when you click on the command line 58, it ceases to be active so that the position of the user's cursor does not change, and the command line cursor 285 becomes active. When you click on the terminal window 56, if the terminal window was inactive, it becomes active so that the value of the user cursor position changes to the value corresponding to the point of pressing the terminal window 56, and the terminal emulator generates terminal commands sent by device 4 to the specified devices connected to device ports 4 corresponding to moving the cursor of the terminal to the point at which the terminal window is currently being pressed. For example, if before clicking on the terminal window 56, the terminal window 56 was inactive, and the value of the user cursor position 286 corresponded to the point of pressing 287 on the terminal window 56, then when you click on the terminal window 56 at point 288, the value of the user cursor position changes to 289 point 288, and the terminal emulator generates terminal commands sent by device 4 to specified devices connected to device ports 4 corresponding to a change in the value of the user cursor position from 286 to 289 .
