Abstract

PURPOSE:To improve the availability of a terminal by securing such constitution where a routine transmitting sentence is registered in each program function key and these registered sentences are transmitted just with operation of each corresponding function key. CONSTITUTION:A routine character string is previously registered in each program function key of a keyboard 26 set at the terminal side from the host side. Under such conditions, either one of program function keys is operated. Thus the character data string corresponding to the operated key is sent to a host computer 20. Therefore, the character data string showing the process to be selected can be informed to the computer 20 just with a single operation of the corresponding program function key in case the computer 20 inquires the selection of the process to be carried out next. Thus it is possible to improve the operability at the terminal side and the availability of a terminal.

Description

[Detailed Description of the Invention] [Table of Contents] Overview Industrial Field of Application Conventional Technology Problems to be Solved by the Invention Means for Solving the Problems Action Examples Effects of the Invention [Summary] The present invention provides a host computer terminal. It is a device that is connected to a computer used as a host computer, and its purpose is to make effective use of the program function keys provided on the keyboard of the terminal side. means for monitoring reception of character data indicating an escape code, means for determining whether or not next received data matches predetermined character data when reception of character data indicating an escape code is confirmed; means for storing the program function key specified in one part of the subsequent received data string in correspondence with the character data formed in the other part when a match is confirmed; and means for transmitting program function keys whose operation has been confirmed and character data stored in correspondence to the host computer.

[Industrial Field of Application] The present invention relates to a computer used as a host computer terminal.

In a multi-user interactive general-purpose operating system, by running a predetermined terminal emulator program on a personal computer, it can be easily used as a terminal for a host computer.

[Prior Art] In this type of computer system, character data (ASCII code) is sent and received between the host side and the terminal side, and therefore, on the terminal side, data sent to the host side is transmitted and received from the keyboard. Input is made by operating character keys or number keys.

[Problem to be Solved by the Invention] Therefore, even when inputting long, complex, and difficult character strings, or frequently used character strings, the operator at the terminal side has to repeatedly operate the number keys and letter keys on the keyboard. It is necessary to do so.

As a result, the operability of the terminal has deteriorated, and a lot of effort and time have been wasted on terminal input.

The present invention has been made in view of the above-mentioned conventional problems,
The purpose of this is to improve the input operability of the terminal by utilizing the program function keys provided on the terminal's keyboard.

[Means for Solving the Problems] In order to achieve the above object, a terminal computer according to the present invention is configured as shown in FIG.

In the figure, means 11 receives character data transmitted from the host computer, and means 12 monitors reception of character data indicating an escape code.

When the means 12 confirms that the character data indicating the escape code has been received, the means 13 determines whether the next received data matches the predetermined character data.

When this means 13 confirms that both data match, the program function key specified in one part of the subsequent received data string and the character data formed in the other part are
4 is correspondingly stored.

In addition, the operation of each program function key is the means 15.
The stored character data is transmitted to the host computer by the means 16 in correspondence with the program function key whose operation is confirmed by the means 15.

[Special characters among the characters sent and received between the working cohost computer and its terminal computer are specified in the range OO to IF in hexadecimal notation, and the escape code (IB in hexadecimal notation) in the special characters The characters following are given special meanings.

Various controls are performed by escape processing using these subsequent characters, but not all characters are used for this processing.

Therefore, by sending an empty, unused character following the escape code, it is possible to cause the terminal to perform special processing.

In the present invention, when character data of a predetermined code (empty character not used in escape processing) is transmitted from a host computer following character data of an escape code,
One of the program function keys is specified by the part of the character data that follows these, and this and the character data formed by the other part are stored in correspondence.

When any function key on the terminal keyboard is operated, character data stored in correspondence with that program function key is transmitted to the host computer.

[Embodiment] Hereinafter, a preferred embodiment of the terminal computer according to the present invention will be described based on the drawings.

FIG. 2 illustrates the overall configuration of the embodiment, in which a terminal emulator program is running on a personal computer main body 22 connected to a host computer 20. In FIG.

By running the program, the personal computer main body 22 is used as a terminal of the host computer 20, and the host computer 20 and the personal computer main body 2
Transmission and reception of character data between the computer and the computer 2 is performed character by character using the TTY procedure.

The character data transmitted from the host computer 20 is displayed on the terminal side display 24, and the character data obtained by operating the terminal side keyboard 26 is transmitted from the personal computer main body 22 to the host computer 20.
being sent to.

In FIGS. 3 and 4, the procedure of processing in the personal computer main body 22 is explained using a flowchart.
In FIG. 3, the character data sent by the host computer 20 is first taken in for one character (step 28).

Next, it is determined whether character data indicating an escape code has been captured (step 30), and if the captured data does not indicate an escape code (No in step 30), the captured data is displayed on the display 24. (Step 32).

When it is confirmed that the captured data indicates an escape code (YES at step 30), the next received character data is captured (step 34).
It is determined whether the captured data indicates the above-mentioned empty character i Z l (step 36).

If it is confirmed that the captured data at that time is not the character IZT (NO in step 36), escape processing is performed in accordance with the character data following the escape code (step 3).

For example, cursor movement control is performed as shown in Figure 5 (A), entire double-sided clearing control is performed as shown in Figure 5 (B), and partial line deletion is performed as shown in Figure 5 (C). It will be done.

Here, first the escape code, then the character "Z'"
If the received data of (steps 30 and 3
6), the received data for two characters is first taken in (step 40), and it is determined which of the program function keys on the keyboard 26 has been designated by the host computer 20 based on the two-phase numbers indicated by the data. (step 42).

Then, character data is imported until the last line feed code shown in FIG. 6 is imported (step 44).
-1...4a-n), the captured data string is written into the area corresponding to the corresponding program function key designated by the host computer 20.

When character data is input from the keyboard and sent to the host computer 20, as shown in FIG. 4, the input data is captured every time the keyboard is operated (step 48), and it is determined whether or not the keyboard input data is based on a program function key. (step 50).

At this time, if it is confirmed that the keyboard input data is not the result of operation of the program function keys but the operation of character keys or number keys (NO in step 50), the character data of the keyboard input is transferred to the host computer. transmitted to computer 20 (step 52)
.

Also, if it is confirmed that the keyboard input is due to the operation of the program function keys (step 5)
0 (YES), character data strings stored in correspondence with the operated program function keys are read out and transmitted to the host computer 20 (step 54).

When any program function key is operated in this way, the character data string corresponding to that operation key is transmitted to the host computer 20, so that the host computer selects the next process to be performed as shown in FIG. 2
0 asks, the corresponding program function key (PFI).

By operating PF2 or PF3 only once, a string of character data indicating the process to be selected is transmitted to the host computer 2.
0 can be notified. Incidentally, in the conventional case, as shown in FIG. 8, two key operations are required: first operating the key with the number indicating the process to be selected and then operating the return key.

Additionally, if a long, complex, difficult, or frequently used sentence is assigned to the corresponding program function key, you can simply press the corresponding program function key and the corresponding sentence will be displayed. Sent automatically.

As explained above, according to this embodiment, a fixed format transmission sentence is registered to each program function key, and the registered sentence is transmitted as is by only operating the corresponding function key. Operability is significantly improved.

As a result, the effort and time required to operate the terminal can be significantly reduced, making it possible to significantly increase the efficiency of using the terminal.

[Effect of the Invention] As explained above, according to the present invention, if a fixed character string is registered in advance by the host side in each program function key on the terminal side keyboard, the corresponding character string can be written by simply operating the program function key. Since the registered character string is automatically transmitted to the host side, the operability of the terminal side can be significantly improved and the time and labor required for the operation can be reduced, and therefore the efficiency of use of the terminal can be greatly increased.
