Description

FIELD OF TECHNOLOGY

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

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 controlled by 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. 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 when developing 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.

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.

The program instructions provide instructions and methods that allow device 4 to implement the method shown in FIG. 8. It displays only the elements that are essential for further consideration. However, it should be understood that other embodiments of the invention may be implemented, which may include additional elements not shown here, or logical changes may be made without deviating from the essence and scope of legal protection of this invention, as set forth in the attached claims.

In subsequent implementations, a connected device refers to devices connected via a serial interface (serial port, communication port, COM), transistor-transistor logic (TTL) interface, command line interface (CLI), USB interface or connected through a wireless transceiver. Examples of such devices include another electronic device 4, a command-line router, a computer sending messages via a serial, USB, or wireless port, or a wireless built-in transceiver, a TTL wireless transceiver such as a TTL Bluetooth wireless transceiver, or a microcontroller board such as an Arduino UNO sending messages via USB port or TTL port, etc. Devices can be electrically connected to other interface converters such as USB / TTL converter, USB / COM converter, TTL wireless transceiver, USB wireless transceiver, etc. In this case, the interface converter is electrically or wirelessly connected to the electronic device 4 for data exchange. In FIG. 3 shows block diagrams of configurations of an electronic device with a touch screen connected to a given device. For example, in FIG. 3, the electronic device 4 establishes a connection 17 through the integrated wireless transceiver 14. In another example shown in FIG. 3, the device 4 is connected to the internal circuit 20 of the microcontroller board 21 by connecting the USB port 11 of the electronic device 4 to the USB port 22 of the microcontroller board 21. In this case, the TTL port 23 of the USB / TTL converter 24 is connected to the internal circuit 20 of the microcontroller board 21 embedded in the microcontroller board 21. In another example, shown in FIG. 3, the electronic device 4 establishes a connection 13 via the TTL port 25 of the USB / TTL converter 26 connected via the USB port 27 to the USB port 11 of the electronic device 4. In another example, in FIG. 3, the electronic device 4 establishes a connection 13 via the TTL port 25 of the USB / TTL converter 26 connected via the USB port 27 to the USB port 11 of the electronic device 4. In another example, in FIG. 3, the electronic device 4 establishes a connection 13 via the COM port 28 of the USB / COM converter 29 connected via the USB port 30 to the USB port 11 of the electronic device 4. In FIG. 4, the computer 31 establishes a connection 13 via the TTL port 25 of the USB / TTL converter 26 connected via the USB port 27 to the USB opt 32 of the computer. In another example of FIG. 4, the computer 31 establishes a connection 13 via the COM port 28 of the USB / COM converter 29 connected via the USB port 30 to the USB port 32 of the computer. In another example shown in FIG. 4, the computer 31 establishes a connection 17 through the built-in wireless transceiver 33. The computer 31 can also establish a connection 17 through a wireless USB transceiver 34 connected via its USB port 35 to the USB port 32 of the computer, or through a wireless TTL transceiver 36 with a TTL port 37 or via a wireless COM transceiver 38 with a COM port 39.

In this case, the connection 13 with the internal electrical circuit 20 of the microcontroller board 21 is established via the TTL port 23 of the USB / TTL converter 24 integrated into the microcontroller board. The connection can also be established via the TTL port of the electrical circuit of the microcontroller board without using a USB / TTL converter 24. For example, the TTL wireless transceiver can be connected to the TTL ports 40 of the electrical circuit 20 via the TTL port 34, after which connection 17 can be established with the electronic device 4, as shown in FIG. 6.

In yet another example, shown in FIG. 7, the router 44 establishes a connection 13 by connecting the rj45 port 45 of the Cisco cable 46 to the rj45 port of the router command line interface 47.

In FIG. 8, FIG. 32, FIG. 33, FIG. 34 is a control block diagram of an electronic device 4. Examples of a user interface according to an embodiment of the invention are shown in FIG. 9-31. 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.

Data received from port 11 of the device is placed in the incoming message memory 48. Data from the incoming message memory 48 is processed by the incoming message converter 49, which generates the resulting display of a separate window of the terminal 50 for incoming messages from the communication port, stored in the memory 51, or the display of the terminal window 52, stored in the memory unit 53, for the selected data display format (text, hexadecimal, binary, etc.) and for the text data display format changes the position to cursor of the terminal shown in block diagram 54. In a text format for displaying data, the incoming message converter 49 also checks the input data memory 48 for the control sequences of the terminal: if a control sequence is found in the sequence of bytes stored in the memory unit 48, this sequence is deleted from of the memory unit 48, and an operation is performed for the terminal emulator in accordance with this control sequence. In the embodiment shown in FIG. 8, 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 14 with port 15. In the embodiment shown in FIG. 8, both cursor positions are included in illustration for one unit 54. Data from the screen memory 53 is used to update the terminal application window 52 of the terminal displayed on the touch screen 6 of the electronic device 4. Pressing the keys of the virtual keyboard 55 changes the terminal window 52 or command line 56 located at the bottom of the screen. The outgoing message processing unit 57 processes the events of the terminal 52 window and returns the terminal window 52 to its last state before keyboard input, and sends the keystroke data to the outgoing message converter 58. The outgoing message processing unit 59 processes the command line changes 56, returns the command line 56 to its last state before entering from the keyboard, and sends data about keystrokes to buffer 60. When you press key 61, located under the terminal window 52 in the lower right corner to the right of the command line 56, as shown in FIG. 21, this data is transmitted by the block 62 to the outgoing message converter 58, and the memory block 60 and the command line 56 are either cleared or not, depending on the processor settings. The processor settings are stored in memory 10. The settings user interface is opened by pressing the menu button 63 located in the menu bar 64 above the terminal window 52. Outgoing message converter 58 generates terminal commands and sends them to the outgoing message memory 65. Data is sent from the memory block 65 through port 11 and connection 13 to port 15 of the connected device 14.

If the local echo 66 mode is enabled in the processor settings, the outgoing message converter 58 also sends a signal to the local echo block 67, which forms a display of the terminal window and updates the memory block 53 to display the echo of user commands in the terminal window 52. In some embodiments, according to According to the invention, in a text data display format, the memory unit 53 stores the data of the terminal window 52 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 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 58 to write a new character to the terminal window 52, the local echo block 67 updates the position of the user cursor to the current 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 58. After that, the value of the user cursor position and the terminal cursor position are updated. When a newline character '\ n' is received from the outgoing message converter 58, the local echo block 67 does not record it in the memory block 53, but updates the value of the terminal cursor position and the value of the user cursor position in accordance with the selected method of processing the end of line character during signal transmission. In some embodiments of the invention, a terminal window 52 is configured to display character strings. Upon request, the terminal window 52 processes the lines from the memory unit 53 and displays them on the screen so that each character of the end of the line '\ n' starts a new line. An example of such an implementation of a terminal window is EditText, 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 66 is turned on or the local echo 66 is turned off but the user cursor option is turned on, then the touch processing unit 68 processes the touch of the screen including movements along the window surface of the terminal 52, sends terminal commands to the outgoing message memory 65 and updates the position of the user cursor. If the window of the terminal 52 loses focus or receives 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 65. 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 69, if both the local echo and the user cursor option are turned off, the touch processing unit 68 does not process touches on the window of the terminal 52 and does not update the position of the user cursor. If the local echo 66 mode is enabled, then the touch processing unit 68 applies the 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 14. The position of the user cursor is used by the touch processing unit 68 to generate 65 terminal commands sent to the memory block of outgoing messages corresponding to pressing the arrow keys, and the position of the terminal cursor is used to determine the current cursor position, where either the character received from the connected device 14 should be placed, or the character entered by the user from the virtual keyboard 55 should be displayed with a local echo. Pressing the basket button 70 in the menu panel 64 clears memory blocks 51, 53 and 60. Pressing the information menu button 71 opens the application information and the log section of the transmitted and received signals. Pressing the menu button 72 starts the connection / disconnection procedure of the device. When no devices are connected and no program settings are selected, the terminal window 52 is inactive. If no devices are connected, pressing the button 72 opens a list of 73 available devices, as shown in FIG. 9. Pressing the menu button 72 again closes the list. Clicking on an item from the list 73, for example, 74, closes the list and an attempt is made to connect the selected device. If successful, the color of the button 72 of the menu bar 64 turns green, and the connection information 75 appears on the screen, as shown in FIG. 10. Clicking on it hides the message 75. After connecting the device 14 and selecting the processor settings, the terminal window 52 becomes active, and pressing the terminal window 52 or command line 56 opens the virtual keyboard 76, as shown in FIG. 11. When you open the virtual keyboard 76, the terminal window 52 changes its size to the area above the keyboard. As the screen rotates from portrait to landscape, terminal 52 and virtual keyboard 76 change orientation, as shown in FIG. 12. Upon rotation from landscape orientation to the book window of the terminal, it returns to the state shown in FIG. 11. If the automatic scaling option is turned on in the application settings, when turning, the font size of the text 77 of the terminal window 52 automatically changes 78 so that the width of the terminal window remains the same in the number of characters and equal to the value defined in the settings of the application, and the terminal window fills the entire screen width devices as shown in FIG. 13. If auto-scaling is turned off, the font size remains equal to the value defined in the processor settings, as shown in FIG. 14. Moreover, if during rotation the new screen width 80 is less than the length of the line of text 81 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 82 is added to the left of the command line 56. Pressing the button 82 switches the outgoing message processing unit 59 and the command line 56 between different display formats (text, hexadecimal, binary, etc.) so that the button 82 displays the designation of the corresponding format (AB, 0x, 0b, etc.) as shown in FIG. 15. In some embodiments of the invention, another button 83 is added in the lower right corner of the window of the terminal 52. Pressing the button 83 switches the outgoing message processing unit 57 and the terminal window 52 between different data display formats (text, hexadecimal, binary, etc.). ) so that the button 83 displays the designation of the corresponding format (AB, 0x, 0b, etc.), as also shown in FIG. fifteen.

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 the hexadecimal format 84, the prefix 0b for the binary format 85). If the input is carried out in the terminal window 52, then after entering the last character of the number in non-text format, the corresponding value is sent by the outgoing message converter 58 to the outgoing message memory 65. When deleting the last character of the number in the non-text format, outgoing message converter 58 sends the code 0x08 to the outgoing memory Messages 65. When deleting other characters of numbers in non-text formats, the outgoing message converter 58 does not generate any signals for the memory block 65. This method allows drive data in formats such as hexadecimal and binary in real time as if they were introduced and removed 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 86 of the virtual keyboard 76, after the last number 87 is completed, the next number entered will be the number of repetitions of the same number sent one after another. If the input is carried out on the command line 56, then after pressing the "." 86, the format designation on button 82 to the left of the command line will turn green. After entering the number, the format designation on the 82 button will turn black. When button 61 is pressed, the corresponding number of repetitions of code 87 will be sent to the connected device.

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.

If the input is carried out in the terminal window 52, then by pressing the "." 86 of the virtual keyboard 76, the format designation displayed on the button 83 in the lower right of the window of the terminal 52 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 "." 86, a prefix starting with a “-” is displayed (for example, the prefix “-0x” 88 is displayed for the number 87 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 repeats of the code will be sequentially sent by the outgoing message converter 58 to the outgoing message memory 65. 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 the hexadecimal number), then the next number of repetitions of the code "0x08" will be sent by the outgoing message converter 58 to the outgoing message memory unit 65. Thus, in order to send N + 1 once the code is 0xab, you must first press "a" and "b", then press the button. 86 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 the local echo 66 is turned on, then when sending sequences from the command line, the local echo block 67 converts them into the view installed in the terminal window 52.

When you erase the last character of a number in a non-text format, starting with a prefix starting with a character, the symbol on the button 83 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 code 87 will be sent (for example, code 87 for hexadecimal format) and the designation on button 83 will turn blue. Otherwise, when you erase the first character of a number starting with a prefix starting with the prefix “-“, the prefix will also be automatically deleted, and the color of the notation on button 83 will turn blue.

In some implementations according to the invention, for convenient access to the set of control sequences, a button 89 is added in the lower left corner of the terminal window 52. When pressed, the control sequence input mode is activated, in which outgoing message processing units 57 and 59 transform the keystrokes of the virtual keyboard 76 into appropriate escape sequences. For example, when you press button A 90, the outgoing message processing unit 57 converts it to the CTRL-A control sequence equal to 0x01, when you press button B, the outgoing message processing unit converts it to the CTRL-B control sequence equal to 0x02, etc.

In some implementations according to the invention, the local echo block 67 and the incoming message transformer 49 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, when you press the send message button 61, before displaying the command line message 56 in the terminal window 52, if the last number in the non-text format is not completed 91, the number is automatically completed by filling in the remaining characters for the input with zeros or by deleting a number depending on the selected settings. When the converter receives 49 messages from the connected device, entering 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 92 and a list of elements 93 are added to the bottom of the terminal window. If the device is connected and the command line 56 is not empty, pressing the button 92 opens a dialog 94, as shown in FIG. 16. When you click 95, a new item is added to list 93. If the text field 96 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 list 93. When you click on button 97, the dialog 94 closes without any additional actions. When you click on a list item 93, for example 98, its value 99 is displayed on the command line 56 and command line 56 switches to the data format in which the value 99 (text, hexadecimal, binary, etc.) was saved, and the button 82 will display the corresponding designation (AB, 0x, 0b, etc.) as shown in FIG. 15. By long pressing the same element 98, a dialog 100 will appear, as shown in FIG. 17. Pressing the button 101 saves the new value of the list item 98. Pressing the button 102 deletes the list item 98. Pressing the button 103 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 embodiment shown in FIG. 18-20, a long press on the button 61 shows / hides the button 92 and the list 93, as shown in FIG. 18 and FIG. 20, and a long press on the button 82 shows or hides the buttons 89 and 83, as shown in FIG. 19 and FIG. twenty.

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 block 65 from the signal converting unit 58, the modem 104 writes to the outgoing message memory block 65 data from the local file 105 and the responses sent to the connected device 14. In case of receiving a file instead of writing data to the converter incoming messages 49 received packets and responses from the connected device 14 are received by the modem 104, and the received information is recorded in the local file 106. To transfer the files to the menu bar 64, a button 107 is added. When you click 1 07, a dialog 108 for transferring files opens over the window of the terminal 52, as shown in FIG. 21. Pressing the button 109 in the upper left corner of the dialogue 108 allows you to select the transfer protocol 110. Button 111 in the lower left corner of the dialogue 108 allows you to select the transmission direction 112. File transfer is activated by pressing the button 113 in the lower right corner of the dialogue. Another click on the button interrupts the file transfer. When transmission starts, line 114 appears under the dialog with information about the status of the transmission, the number and percentage of transmitted bytes and the average transmission speed. A download bar 115 is also displayed to visually display the percentage of transmitted data. When transferring the file, pressing the button 113 displays a list of files 116 located in the local directory, for example / UDevTerm / Sent, as shown in FIG. 22. Clicking on a list item, for example, 117, selects the appropriate file for transfer. If file acquisition is selected, pressing the button 113 depending on the selected protocol may display a dialog 118 for selecting the name of the file to be saved, as shown in FIG. 23. For example, this option can be used when receiving a file without a protocol and using the Xmodem protocol. Line 119 contains the name of the file to be written to, located in the local directory, for example, in / UDevTerm / Save. When you click 120, the application will try to create the appropriate file. When button 121 is pressed, file reception will be canceled. If the file already exists, pressing button 120 for any protocol displays a dialog 122 asking whether to overwrite the file, as shown in FIG. 24. When you click 123, the file information will be deleted. When you press 124, file acceptance will be canceled. The following sequence of actions can be used to send / receive a file. First, a button 107 is pressed to open a file transfer dialog 108. Secondly, a button 109 is pressed to select the desired protocol 110. Thirdly, a button 111 is pressed to select a transmission direction 112, a button 113 is pressed to start a transmission. 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 108 can be hidden by pressing the menu button 107 of the panel 64. The button 107 changes to 126 during transmission and 127 during reception to inform the user of the transmission status if the dialogue 108 is hidden, as shown in FIG. 25. Button 107 returns to its original form 125 upon completion of transmission.

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 128 has been added to menu bar 64, as shown in FIG. 26. When you click on it, window 129. opens. This window may contain various mathematical tools, for example, it may contain fields 130, 131, 132 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 133 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 134, the CRC value in hexadecimal format is displayed in field 135.

In some embodiments of the invention, a separate terminal window 50 for received messages is added, as shown in FIG. 27. The windows of the terminals 52 and 50 have separate memory blocks, the memory block 51 for the terminal 50 window is filled with the incoming message converter 49, and the memory block 53 for the terminal 52 window is filled with the local echo block 67. For the same display of data in both windows, the buttons 83, 89 92 and a list 93 located at the bottom of the window 52 for non-windowed embodiments 50 are moved to a line dividing the windows of the terminals 50 and 52, as shown in FIG. 27. 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 67 for the terminal window 52, and the position of the terminal cursor is now used only by the incoming message converter 49 for the terminal window 50. Pressing the button 83 switches the display of data of the terminal window 52 between different presentation formats (text, hexadecimal, binary, etc.). Pressing the button 82 switches the presentation format of the command line data 56. For embodiments with the terminal window 50, this pressing additionally switches the display of the terminal window 50 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. 13 and FIG. 14. FIG. 28 shows an application for arranging a screen 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 136 and 137. For a terminal with terminal window 50, switch 136 connects an inbound message converter 49 with a memory unit 51 for the terminal window 50, and the switch 137 is open so that the terminal cursor position is used only by the incoming message converter 49 for the terminal window 50. For t rminala without the switch 136 connects the terminal box 50 incoming messages converter 49 and memory unit 53 for the terminal box 52, and the switch 137 is closed so that the position of the user and the cursor and the position of the cursor used by the terminal unit 67 through the local echo block 54.

In some embodiments according to the invention, for a terminal with a terminal window 50 in text format, upon receipt of a terminal command from the memory unit 48 corresponding to pressing the arrow button, the incoming message converter 49 updates the position of the terminal cursor. If the command to write a new character to the terminal window 50 is received, the input signal converter 49 uses the current value of the terminal cursor position to update the terminal window 50, and then updates the terminal cursor position. In some embodiments according to the invention, for a terminal with a terminal window 50, the memory unit 51 stores the data of the window of the terminal 50 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 unit 48, the incoming message converter 49 updates the position of the terminal cursor. Upon receipt of instructions for writing a new character to the terminal window 50, the incoming message converter 49, 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 48. Then, the position of the terminal cursor is updated. Upon receipt of a character sequence selected from the memory unit 48 as the new line sequence in the application settings, the incoming message converter 49 does not record this sequence in the memory unit 51, but updates the position of the terminal cursor. In some embodiments of the invention, the window area of the terminal 50 is configured to display character strings. When requested, the terminal window 50 processes the lines from the memory unit 51 and displays them on the screen, each character '\ n' starts 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 50, in a textual representation, upon receipt of a terminal command corresponding to the arrow button from the incoming message memory unit 48, the incoming message converter 49 updates the position of the terminal cursor and the position of the user cursor. Upon receipt of an instruction to write a new character to the terminal 52 from the memory unit 48, the incoming message converter 49, using the cursor position of the terminal, updates the terminal window 52 and then updates the position of the terminal cursor.

In some embodiments according to the invention, for a terminal without a terminal window 50, the memory unit 53 stores the window data of the terminal 52 in a text format 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 value of 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 48, the outgoing message converter 49 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 48 for recording a new character in the terminal window 52, the incoming message converter 49 updates the position of the user cursor to the current value of the terminal cursor position, uses 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 incoming message memory unit 48. After that, the position of the user cursor and the position of the terminal cursor are updated. Upon receipt of a character sequence selected from the memory unit 48 as the new line sequence in the application settings, the incoming message converter 49 does not record this sequence in the memory unit 53, 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 52 is configured to display character strings. Upon request, window 52 processes the lines from the memory unit 53 and displays them on the screen, each character '\ n' starts a new line. An example of such an implementation of a terminal window is EditText, a subclass of the Android Text View class.

In some embodiments according to the invention, the developed terminal algorithm is configured to work with various communication ports such as USB and wireless communication ports of an electronic device. For example, communication with a given device can be established via the Bluetooth port of an electronic device. In this case, the following method for establishing a connection is provided. Pressing the menu button 72 opens a dialog 138 with an automatically updated list 139 of detected Bluetooth devices, as shown in FIG. 29. Pressing the button 140 allows you to choose between connecting to the device as a client or host 141. To establish a connection with one of the devices, you must first pair the specified device 18 and electronic device 4. To do this, select one of them, for example, 142, and request pairing by long pressing on 142. If successful, the pairing dialogs will appear on the screen of the electronic device 4 and the specified device 18. After confirming both dialogs, if the pairing was successful, the user is informed used this color text line 142 green. Now it is possible to establish a connection with the given device by a single click on line 142. (If instead of this, once again, long press on line 142, the devices will be disconnected and the color of line 142 will change to black). When connecting to electronic device 4 as a client, it is necessary to establish a server connection on the specified device 18. When connecting electronic device 4 as a server, after pressing line 142, dialog 138 disappears and message 143 appears informing that electronic device 4 is waiting for the device to be connected as client, as shown in FIG. 30. If you want to interrupt further connection, when you click on button 72, the connection will be interrupted. To connect a given device 18 as a client, it is necessary to create an outgoing virtual serial port on it for electronic device 4 and connect to electronic device 4 through this port. If the connection is successful, the user will be informed about this by changing the color of the menu button 72 to green. To close the Bluetooth connection, press the button 72 again.

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 and 17 through ports 11 and 16 with devices 14 and 18 (for example, one connection via a USB port and one via a virtual Bluetooth serial port). Both terminal emulators 144 and 145 operate independently so that one of them displays information and receives information from the user, while the other operates in the background. The switching between terminal emulators shown in the block diagram of FIG. 8 by switches 146-151 can be carried out, for example, by long pressing the menu button 72, in which the button changes its appearance to 152 or 153 depending on which terminal is currently displayed, as shown in FIG. 31.

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 65 and 156 and the memory blocks of the incoming messages 48 and 157 are connected via the connection control unit 158, as shown in FIG. 8. Connection control unit 158 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 72 is required, after which the button changes its appearance, for example, to 155, 152, 153 for different ports, and finally to the image 154, indicating a direct connection of ports. If the connection between the ports is not established, the button 72 is colored yellow. If a connection with devices 14 and 18 is established, a single press of the button 72 turns off the emulators of terminals 144 and 145 and creates a direct connection between ports 11 and 16 by connecting the memory blocks of outgoing messages 65 and 156 and the memory blocks of incoming messages 48 and 157 through the connection control block 158 , and the color of the button 72 turns green. Another click on the button 72 closes the connection between ports 11 and 16 and turns on the terminal emulators 144 and 145, connecting the outgoing message memory block 65 to the outgoing message converter 58 and the touch processing unit 68, the incoming message memory block 48 to the incoming message converter 49, block the memory of outgoing messages 156 to the converter of outgoing messages 159 and the touch processing unit 160, the memory block of incoming messages 157 to the converter of incoming messages 161.

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 104 and 162 perform simultaneous independent file transfer via ports 11 and 16 of the electronic device 4.

In some embodiments of the invention, as shown in the block diagram of FIG. 8, the switch 163 corresponds to the method of attaching the incoming message memory unit 48 to either the incoming message converter 49 of the terminal emulator, or to the modem 104 for receiving files and responses from the device 14 in case of file exchange, or to the connection control unit 158 for direct connection of ports between devices 11 and 16. The switch 164 corresponds to the method of attaching the outgoing message memory block 65 to either the outgoing signal converter 58 of the terminal emulator or to the modem 104 for transferring files and responses to the device 14 in the case of file exchange, or to the connection control unit 158 for direct connection of ports between devices 14 and 18. The switch 165 corresponds to the method of connecting the touch processing unit 68 to the outgoing message memory unit 65 to turn on the unit when using the terminal emulator or turn off the unit when transferring files or direct communication between ports 11 and 16.

FIG. 32 shows a functional diagram with steps for configuring an interface converter connected to a USB port of an electronic device, in accordance with one embodiment of the invention. At step 166, a list of available USB devices is requested. If list 167 is not empty, the next step 168 selects a device from this list and reads the values of the source and receiver points (out Endpoint, in EndPoint), the manufacturer identifier (vendor ID, VTD), and the product identifier (product ID, PID). Otherwise, if the list is empty, the connection is not established 169, and the configuration process ends. If the device was successfully selected, then the next step 170 establishes a connection with the device. If the device has already been disconnected 171, then the connection is not established 169, and the configuration process ends. If the connection is established 172, the next step 173 reads the number of bytes available for the data packets of the source and receiver points. In the next step 174, the connection is considered established and the configuration process ends.

FIG. 33 shows a functional diagram with steps for configuring a virtual Bluetooth serial port for a server, in accordance with one embodiment of the invention. In step 175, a server socket is created for a serial connection. If the socket was successfully created 176, a cycle begins to wait for incoming connections 177. Otherwise, the connection is not established 178 and the configuration process ends. Upon receiving an incoming connection, the server accepts it 179. In case of an error 180, the connection is not established, and the configuration process ends. Otherwise, if the connection is established 181, in the next step 182, the server tries to receive inbound and outbound socket data streams. In case of error 183, the connection is interrupted and the configuration process ends. Otherwise, the connection is considered established 184 and the configuration process ends.

FIG. 34 shows a functional diagram with steps for configuring a virtual Bluetooth serial port for a client, in accordance with one embodiment of the invention. In step 185, a serial connection socket is created. If creation was successful 186, then an attempt is made to connect to the specified device. Otherwise, the connection is not established 187 and the configuration process ends. The process ends even then, if an error 189 occurred while trying to connect 188. If the connection 190 is established, then in the next step 191 the client tries to receive the incoming and outgoing socket streams. In case of error 192, the connection is closed and the configuration process ends. Otherwise, the connection is considered established 193 and the configuration process ends.

FIG. 35 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 194, incoming messages are expected to be received. Loop 194 is executed until no messages are received or received messages 195 contain 0x43 and 0x15. If a 196 0x15 message is received, then the protocol for 8-bit Cyclic Redundancy Check (CRC) 197 values is used, and a 198 0x06 0x15 response is sent to the connected device. If 199 0x43 message is received, then a protocol with 16 bit CRC values of 200 is used, and 201 response 0x06 0x43 is sent to the connected device. After step 198 or step 201, in a loop, step 202 is performed to read data from a file. Until the file is finished reading, step 203 is performed to transmit packets to the connected device containing the header, data from the file, and a CRC value for error detection. After each packet is sent, a 204 response is expected from the connected device. Upon receipt of a 205 0x06 response from the connected device, the previous transmission is considered successful and the execution of step 202 is repeated. Upon receipt of a 206 0x15 response from the connected device, the previous transmission is considered unsuccessful and the packet is sent again 203. Upon receipt of 207 eight consecutive bytes 0x18 and eight consecutive bytes 0x08 from the connected device, the same sequence is sent 208 to the connected device and transmission is interrupted. The same sequence 208 is sent to the connected device if the user decides to abort the transfer 209. If the file is finished reading, the connected device 210 sends a 0x04 message and the transfer ends. FIG. 36 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, timer 211 is started so that at regular intervals 212 code 0x15 is sent to the connected device if 8-bit CRC values are used, or 0x43 if 163 CRC values are used. During the execution time of the cycle 211, the port of the electronic device is checked for responses 214 from the connected device. The loop continues until a response of 0x06 0x15 or 0x06 0x43 is received. Upon receipt of a 215 response 0x06 0x15 or upon receipt of a 216 response 0x06 0x43, a cycle is started with step 217 to read data received from the connected device. Upon receipt of 218 0x04 messages from the connected device, the file reception is considered complete and the process ends after 219 sends a 0x06 response to the connected device. Upon receipt of 220 eight consecutive bytes 0x18 and eight consecutive bytes 0x08 from the connected device, the same sequence is sent to 221 connected devices and the reception of the file is terminated. Otherwise, the packet header, data, and CRC value of 222 are received. Reading continues 223 until 224 known number of bytes of the packet are received. After that, the CRC value of 225 for the obtained data is calculated and 226 is compared with the obtained value. If these two values coincide, then the 227 code 0x06 is sent to the connected device and then step 217 is performed. Otherwise, if the CRC values do not match, 228 0x15 code is sent to the connected device.
