Abstract

PURPOSE:To automatically start a specific emulation program under the recognition of a host computer by transmitting plural specific commands to the host computer while checking a connecting state with the host computer. CONSTITUTION:When the start of a specific emulation program is specified from a keyboard 4, a controller 1a transfers a command to the host computer in order to confirm the connecting state with the host computer and waits an I/O request instruction to the command to confirm the connecting state with the host computer. Plural specific commands, especially specific commands to be optionally set up, are read out from a disk device 3 and automatically transmitted to the host computer. Then, the specific emulation program is executed on the basis of a response state to the plural specific commands from the host computer.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a terminal emulator that executes a specific emulation program on a computer device connected to a host computer.

[Conventional technology]

Conventionally, this type of device is equipped with a terminal emulator that allows a computer device equipped with hardware having a different architecture from that of a host computer to function as a specific computer device using a specific emulation program.

(Problem to be Solved by the Invention) However, when a host computer supports multi-users, it is necessary to recognize the connected terminal emulator. The process remains in the device initialization process.

In order to actually start a specific emulation program, the user is entrusted with the process of logging into the specific emulation program to be started using an input means of the terminal device, such as a keyboard.

For this reason, it takes a considerable amount of time to actually start a specific emulation program, resulting in a problem in that the processing efficiency of the entire terminal device is significantly reduced.

This invention was made to solve the above problems, and by sending multiple specific commands to the host while establishing a connection with the host, it automatically starts a specific emulation program when the host is recognized. The purpose is to obtain a terminal emulator that can.

[Means to solve the problem]

The terminal emulator according to the present invention includes a command sending unit that automatically sends a plurality of specific commands to the host computer while checking the connection state with the host computer;
A program start control means is provided for executing a specific emulation program based on a response state from the host computer to the command transmission means.

Further, the plurality of specific commands may be arbitrarily set and configured to be automatically sent to the host computer.

[Operation] In the present invention, when a command is given to start a specific emulation program, the command sending means automatically sends a plurality of specific commands to the host computer while checking the connection state with the host computer. and,
A program start control means executes a specific emulation program based on response states to a plurality of specific commands from the host computer.

Note that at this time, the command transmitting means transmits a specific command that can be arbitrarily set to the host computer.

(Embodiment) FIG. 1 is a block diagram illustrating the configuration of a terminal emulator showing an embodiment of the present invention. Reference numeral 1 denotes a computer device, which is interfaced with a host computer (not shown). The computer device 1 has a controller 1a that processes data etc. input from a host computer based on a specific emulation program stored in the disk device 3 or internal memory.

A CRT display device 2 displays command data and the like input from the host computer or keyboard 4.

Note that when the controller 1a receives a command from the keyboard 4 to start a specific emulation program, the controller 1a issues a command,
For example, transfer CR (ODH) to the host computer,
By waiting for a manual request command in response to this command, the connection state with the host computer is confirmed. Then, a plurality of specific commands, especially arbitrary settable specific commands, are read from the disk device 3 and automatically transmitted to the host computer. Then, a specific emulation program is executed from the host computer based on response states to a plurality of specific commands.

Next, the automatic starting operation of the emulation program according to the present invention will be explained with reference to FIG.

FIG. 2 is a flowchart illustrating an example of an emulation program automatic start processing procedure according to the present invention. Note that (1) to (lO) indicate each step.

First, the controller 1a controls the CRT display device 2.
Initialize the communication system such as the screen and interface (1).

Next, a command, for example CR (ODH), is sent to the host computer in order to confirm the connection state with the host computer (2).

Next, it is determined whether an input request, which is a response signal to a command sent from the host computer, has been received 3). If NO, it is recognized that the computer device 1 is not connected to the host computer, and a predetermined Execute error handling (10).

On the other hand, if the judgment in step (3) is YES or S, access the disk device 3 and read the file in which the specific command has been written. 4) Determine whether the command reading is normal or not 5) , if No, proceed to step (10), and if YES, send a specific read command, for example, a command corresponding to the log input from the keyboard 4 to the host computer (6
) Next, the host computer waits for receiving an input request that is a response signal to the command sent from the host computer.
), upon receiving it, the controller 1a judges whether the read file is finished 8), and if NO, step (
Returning to step 4), if YES, the normal emulation processing routine is executed (9).

(Effects of the Invention) As explained above, the present invention provides a command transmission means for automatically transmitting a plurality of specific commands to a host computer while checking the connection state with the host computer, and a response from the host computer to the command transmission means. Since a program startup control means for executing a specific emulation program based on the status is provided, the emulation program can be started without performing command input processing that had to be input after the terminal device is connected to the host computer. can. Therefore, the burden of key operations for login by the operator is reduced, and data processing from the host can be efficiently executed.

Furthermore, since the configuration is such that a plurality of specific commands are arbitrarily set and automatically sent to the host computer, unique commands can be set for each terminal device.

Therefore, specific commands can be sent even to hosts that support multi-users, providing excellent effects such as building a more versatile system.
