DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an evaluation device for a terminal communication control device according to an embodiment of the present invention.

The evaluation device 3 of the present invention is connected to a terminal communication control device 2 through a terminal line 5, and the terminal communication control device 2 is connected to a host computer 1 through an I/O interface 4.

The evaluation device 3 includes a receiving circuit 6 that receives data sent from the terminal communication control device 2, a data buffer 7 that stores the data received by the receiving circuit 6, and a data buffer 7 that stores the data stored in the data buffer 7. Among them, a command search unit 8 that searches for command data, a response data storage memory 10 that stores response data to the terminal communication control device 2 corresponding to this command, and a response based on the value of the command searched by the command search unit 8. An addressing circuit 9 that specifies the address of the data storage memory 10, a memory read circuit 11 that reads data from the response data storage memory 10, and a terminal communication control device 2 that reads data read from the response data storage memory 10. Transmission circuit 1 to send to
It consists of 2.

Next, the operation of the evaluation device 3 will be explained.

It is assumed that the response data storage memory 10 stores in advance data to be responded to a command sent from the terminal communication control device 2. A certain I/O program is issued from the host computer 1 and sends data to the evaluation device 3.

Data sent from the host 1 via the terminal communication control device 2 is received by the receiving circuit 6 and stored in the data buffer 7. A command search unit 8 searches for a command from among the data in the data buffer 7, and an address designation circuit 9 designates a read address of the response data storage memory 10 based on the value of the command. Next, the memory reading circuit 11 makes read access to the response data storage memory 10, and the transmitting circuit 12 sends the read data to the terminal communication control device 2.

Through the above operations, data is transferred from the host computer 1 to the evaluation device 3, and data in response is sent from the evaluation device 3 to the host computer 1. Furthermore, if the data stored in the response data storage memory 10 is the response data of a certain terminal device, the terminal communication control device 3 can be evaluated without actually having a terminal device. If data for all types of terminal devices is prepared as data stored in the response data storage memory 10 in advance, evaluation of all terminal devices can be performed by the evaluation device 3.

[0013]

As explained above, the present invention enables evaluation of a terminal communication control device that controls a terminal device using an evaluation device that stores the actual I/O operations of the terminal device in advance. As a result, we can expect the effect that evaluation can be performed without using an actual terminal device.

[0014] Another advantage is that evaluation can be performed without preparing many types of terminal devices.
