A terminal device is made up of a flexible disk, a CRT (A1%), and a keyboard.

In addition to the cluster controller (1), this cluster system also has a processor (

The main functions of the cluster controller (Ha) are data communication with the host computer (not shown), and communication with each workstation (
The main purpose of this task is to perform disk management that allows each workstation to share the fixed disk.

The main functions of the workstation (RI) are the flexible disk (5), CRT (+1) and keyboard (RI).
This involves local data processing using the input/output device, and data transmission and reception to the host computer via the coaxial cable (3), the cluster controller (c), and the communication line (ff+).

In Figure 1, the queue buffer (/j) is used when the operator presses a key from the keyboard (71) while the display control program (/6) is processing an event notification from the coaxial interface program (/2). , is a first-in, first-out buffer that temporarily stores and holds key code strings.

[Problem that the invention seeks to solve]

Conventional workstations were configured as described above, so when the program load is completed after the power is turned on, the workstation is in a state of waiting for command input from the operator (waiting for key input), so the workstation can be used for the host computer. An operator must input a command to notify the status (logon command) or to start executing a local processing program, which increases the burden on the operator, delays the start of use, and causes problems with the man-machine interface.

The present invention has been made to solve the above-mentioned problems, and aims to improve the man-machine interface by eliminating command input operations by an operator after power is turned on in a terminal device.

[Means for solving problems]

Referring to FIG. 1, the terminal device according to the present invention executes a program (two programs) that generates a key code string corresponding to an initial command manually inputted by two operators immediately after program loading is completed after power is turned on. Shite queue buffer (15)
The key code string is temporarily stored in the key code string, and the command contents corresponding to the key code string are executed.

[For production]

In the terminal device according to the present invention, after the power is turned on and the program load is completed, instead of the operator manually inputting the initial command from the keyboard, the terminal device itself generates a simulation of the initial command input and responds to the command. Run the program.

[Embodiments of the invention]

FIG. 1 is a software configuration diagram of a workstation control program (20) of a workstation in an embodiment of the terminal device according to the present invention.

The same or equivalent parts as in the prior art are given the same reference numerals, and the explanation thereof will be omitted. In this workstation control program (20), (22) is a key code generation program that generates a predetermined key code string and inputs it to the cuno (sofa (/S)).

The operation of an embodiment of the terminal device of the present invention having the above configuration will be explained with reference to FIG.

When power is turned on to the workstation (GL) that constitutes the terminal device (step S/ in Figure 2), the coaxial interface program (12), display control program (/b),
Keyboard control program (Ha.

The local processing program (/ri) and the key code generation program (λ2) are loaded from the flexible disk (ri) into the processor (not shown) in the workstation (ri) (8.2). This program loading operation is automatically executed by the hardware of the workstation (IIl) as soon as the power is turned on.

The above loaded programs start running except for the local processing program (/7), but at this time, the key code generation program (here) starts running last (same 8).
3). The last started key code generation program (2
For example, generate a key code string for a command to start a local processing program.

Input the key code string to the queue buffer (/) (5tI).

The display control program (/6) sequentially reads and processes the key code string input from the program (22) to the queue buffer (15), and determines that it is a command for starting the local processing program (S t ). Start the local processing program (/ri) (S6'
). When the operator manually inputs the command for starting the local processing program from the keyboard (7), the key code string is similarly input to the queue buffer (/) each time the operator presses a key.

The display control program (/6) reads and processes it.

Therefore, the key code string input to the queue buffer (15) is the same whether it is input from the key code generation program (-1) or from the keyboard control program (/). However, the key code generation program (Yλ) stores the key code strings in a queue buffer (
15), but the keyboard control program (C) sends seven key codes to the queue buffer (15) when the operator presses a key. However, the display control program (15) Since the key codes are read and processed seven at a time, there is no problem in operation.

The key code string for the local processing program (/ri) startup command generated from the key code generation program (2) can be generated by the keyboard control program (III) by pressing a specific key on the keyboard (ri). This is the same key code string as in the conventional case.

In the above embodiment, the key code generation program (22
) has generated a key code string for the local processing program (/7) startup command, but if you generate a key code string for the logon command to the host computer, it will be automatically executed when the program load is completed after the power is turned on for the workstation (Shitsu). A logon command from the workstation (4'l column) can be sent to the host computer via the cluster controller (c), thereby freeing the operator from troublesome logon operations.

In addition, although the above embodiment describes the case of a terminal device consisting of a cluster controller (HA) and a workstation (RI), a standalone system (workstation) in which the coaxial interface program (/KO) is replaced with a transmission control program (RI) is explained. The station may have a host computer connection function), and the same effect as the above embodiment can be achieved.

〔Effect of the invention〕

As described above, according to the terminal device according to the present invention, a key code generation program is provided that generates the same key code sequence as when the operator inputs an initial command key, and this program is started when the program load is completed after power is turned on. By doing this, the initial command is automatically executed, which simplifies the manual operation of the keys, and has the effect of quickly improving the man-machine interface function.
