The present invention provides a terminal device control method for a computer system in which a host computer and a real terminal device are connected. By performing input/output according to the operation procedure for the terminal device status, terminal operations can be simplified and automated without increasing the load on the host computer, and the input/output format can be changed to suit the user. This is what I did.

[Conventional technology]

Conventionally, the control of terminal devices in electronic computer systems is
This was done using software that performed input/output to and from the host computer according to predetermined procedures.

[Problem that the invention seeks to solve]

The conventional terminal device control described above is controlled by software that performs input/output according to predetermined procedures with the host computer, so commands can be automatically input, but input/output formats such as screen layout etc. The disadvantage is that in order to implement changes, large-scale changes to the control software itself are required.

The present invention eliminates these drawbacks, and allows for automatic command input, screen layout changes, and host computer responses when performing input/output to a terminal device without changing conventional control software. The purpose of this invention is to provide a control method that can automatically input corresponding commands.

[Means for solving problems]

The present invention provides a terminal device for a computer system in which a host computer and a real terminal device are connected via a communication line, and the terminal device includes means for causing the host computer to perform input/output with the real terminal device according to a predetermined procedure. In the control method, a virtual terminal device that executes procedures equivalent to the real terminal device at high speed is provided at an interface connecting the real terminal device and the host computer, and a virtual terminal device that executes procedures equivalent to the real terminal device at high speed is provided, and a The present invention is characterized by comprising terminal control means for executing input/output according to the speed of the actual terminal device.

[Effect]

Input/output between the host computer and the virtual terminal device is performed by conventional software, responses from the virtual terminal device are transmitted to the real terminal device by the terminal control means, and information operated on the real terminal device is also transferred to the virtual terminal by the terminal control means. Communicate to the device. At this time, according to the definition given to the terminal control means, operations are performed depending on the status of the virtual terminal device, a screen different from the screen on the virtual terminal device is displayed on the real terminal device, and information is added to the information input on the real terminal device. The information is attached and input to the virtual terminal device.

This makes it possible to simplify and automate terminal operations without increasing the load on the computer.
The input/output format can be changed to suit the user.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The embodiment of the present invention has a host computer 1 and a real terminal device 4.
are connected via a communication line 5, and the host computer 1
includes a means for executing input/output with the real terminal device 4 according to a predetermined procedure, and further includes a means for performing input/output with the real terminal device 4 according to a predetermined procedure, and further includes a means for executing the same procedure as the real terminal device 4 at high speed in the interface connecting the real terminal device 4 and the host computer 1. The present invention includes a virtual terminal device 2 that executes operations at different speeds, and a terminal control means 3 that executes input/output between the virtual terminal device 2 and the real terminal device 4 in accordance with the speed of the real terminal device.

Next, the operation of the embodiment of the present invention configured as described above will be explained. FIGS. 2 and 3 are diagrams for explaining the operation of the embodiment of the present invention.

When the activation signal is sent from the host computer 1 side, as shown in FIG. 1 transmits No. 1 data to the virtual terminal device 2 by this signal, and the virtual terminal device 2 returns a print completion signal to the host computer I. Such transmission and reception is repeated at high speed between the host computer 1 and the virtual terminal device 2 up to NO, n data.

The real terminal device 4 is activated by the activation signal transmitted from the virtual terminal device 2 and sends a ready signal back to the virtual terminal device 2. In response to this ready signal, the virtual terminal device 2 transmits the already received No. 1 data to the real terminal device 4, and the real terminal device 4 that receives this performs printing and transmits a print completion signal to the virtual terminal device 2.

Such transmission and reception is repeated until the NcLn data is received.

Further, when data is manually input from the real terminal device 4 side, the virtual terminal device 2 receives the data and sends a reception completion signal to the real terminal device 4, as shown in FIG. This transmission and reception is repeated until all data has been transferred.
When the real terminal device receives notification from the virtual terminal device 2 that all data reception is complete, it transmits an operation command to the virtual terminal device 2, and the virtual terminal device 2 transfers all the received data to the host computer 1. When the host computer l receives all the data, it sends an all-data reception completion signal to the virtual terminal device 2 and waits for the next operation command.

Until the virtual terminal device 2 receives key human power from the real terminal device 4 and transfers all data, the host computer 1 can execute other processing.

Next, the operation of the terminal control means 3 that controls the transmission and reception of such signals will be explained.

When used in the same manner as before, the terminal control means 3 transfers the screen data output from the host computer 1 to the virtual terminal device 2 via the communication line 5 to the screen of the real terminal device 4 as it is, Further, the terminal control means 3 transfers the data manually entered to the real terminal device 4 to the virtual terminal device 2 as is.

When changing the screen layout or input format, the changes are defined in advance for the terminal control platform 3 and output from the host computer 1 to the virtual terminal device 2 via the communication line 5. The terminal control platform 3 extracts data from the screen data according to the definition contents,
The screen is transferred to the screen of the actual terminal device 4 according to the defined screen layout. Further, data entered manually into the real terminal device 4 is changed in format by the terminal control means 3, inputted into the virtual terminal device 2, and transferred to the host computer 1 via the communication line 5.

In the case of automatic execution, the screen data output from the host computer 1 to the virtual terminal device 2 via the communication line 5 is controlled by the terminal according to the automatic execution procedure defined in advance for the terminal control platform 3. The Hirai Dan 3 checks and outputs the response results to the virtual terminal device 2 according to the automatic execution procedure, and performs input/output to the real terminal device 4 according to the automatic procedure.

〔Effect of the invention〕

As explained above, according to the present invention, operations are performed depending on the status of the virtual terminal device, a screen different from the screen on the virtual terminal device is displayed on the real terminal device, and additional information is added to information entered manually on the real terminal device. This has the effect of simplifying and automating terminal operations without increasing the load on the host computer, and allowing input/output formats to be changed to suit the user. .
