2. Description of the Related Art Conventional remote maintenance of a minicomputer is performed using a remote maintenance terminal device 1 that inputs hardware or software commands to a minicomputer 8a from a remote value connected via a line, as shown in FIG. , a line control unit 3 located in the remote maintenance dedicated terminal device 2a and having a communication control function with the remote maintenance dedicated terminal device 1; and input from the remote maintenance dedicated terminal device 1 via this line control unit 3. The system control device 6 analyzes the received hardware control commands and controls the hardware of the minicomputer 8a, and the software commands input from the remote maintenance dedicated terminal device 1 via the line control section 3 are sent to the minicomputer 8a. An input/output control device 7 serving as an interface for passing to the remote maintenance dedicated software 11a, a system console 5 for inputting system control commands, and an interface for passing system control commands input from the system console 5 to the system control software 10a of the minicomputer 8a. It is composed of an input/output control device 12.

Next, these operations will be explained.

When the remote maintenance dedicated terminal device 1 accesses the minicomputer 8, the remote maintenance dedicated terminal device 1 instructs whether to access hardware or software. The line control unit 3 of the maintenance-only terminal device 2a switches the other party according to the instructions. When accessing hardware, the path is switched to the system control device 6, and hardware information is collected by commands to the system control device 6. In addition, when accessing the software, the path is switched to the input/output control device 7, and the remote maintenance dedicated software 11a
Collect software information by entering commands to .

[0005] The system console 5 is an input/output control device 1
system control software 10 that inputs and receives system control commands through system control software 10;
a analyzes commands and controls the entire minicomputer 8a.

[0006]

[Problems to be Solved by the Invention] In this conventional remote maintenance configuration for minicomputers, it is necessary to add one input/output control device for remote maintenance. This was a hindering factor.

[0007] In order to improve this, a system console was placed under the remote maintenance control device, which eliminated the need to prepare a new input/output control device for remote maintenance. There is only one line control unit that is connected by a line to the remote maintenance controller, and one input/output control device that serves as an interface between the remote maintenance dedicated software, the system console, and the system control software. If you simply switch the hardware and software paths as shown in the section above, the system console and remote maintenance terminal device will be considered the same thing from the software perspective, so the remote maintenance software and system control software will need to be separated separately. There was a problem that it became impossible to control.

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

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

In this embodiment, a terminal device 1 dedicated to remote maintenance is used to input hardware or software commands to the minicomputer 8 from a remote location connected by a line.
and a line control unit 3 located in the remote maintenance control device 2 and having a communication control function with the remote maintenance dedicated terminal device 1.
and a system control device 6 that analyzes the hardware control commands input from the remote maintenance dedicated terminal device 1 via the line control section 3 and controls the hardware of the minicomputer 8, and inputs the system control commands. system console 5; A data transmission/reception control section 9 located in the computer 8 that distinguishes data between the remote maintenance dedicated software 11 and the system control software 10 and inputs and outputs data to and from the input/output control device 7.
It is made up of.

Next, the operation of this embodiment will be explained.

First, upon access from the remote maintenance dedicated terminal device 1, the line control section 3 in the remote maintenance control device 2 switches the path to the system control device 6 and the data transmission/reception control section 14 and outputs data. Here, the operation on the path to the system control device 6 is the same as that described in the section of the prior art, and will therefore be omitted.

[0014] Remote maintenance dedicated software 11 and system control software 1 in the minicomputer 8
Data input/output control between the remote maintenance terminal device 1 and the system console 5, which are connected to the line control unit 3 via a line, is controlled by the data transmission/reception control unit 9 in the minicomputer 8 and the remote maintenance control unit 2. This is performed with the data transmission/reception control unit 4 located at

In the remote maintenance dedicated terminal device 1, when a data input request is issued from the remote maintenance control device file 11 of the minicomputer 8, the data transmission/reception control section 9 that has received the input request transmits data within the remote maintenance control device 2. A control signal, for example, a 1-byte control code, indicating that there is an input request to the remote maintenance terminal device 1 is transmitted to the data transmission/reception control unit 4 of the remote maintenance terminal device 1 . Upon receiving the 1-byte control code, the data transmission/reception control unit 4 instructs the line control unit 3 to relinquish the transmission right and to enable input from the remote maintenance terminal device 1. Data input from the remote maintenance dedicated terminal device 1 that has become input-enabled is sent to the data transmission/reception control section 4 via the line control section 3 of the remote maintenance control device 2. The data transmission/reception control unit 4 adds a 1-byte control code to the beginning of the data to indicate that the data is input from the remote maintenance terminal device 1, and controls the data transmission/reception within the minicomputer 8 through the input/output control device 7. The input data is sent to section 9. Then, the data transmission/reception control unit 9 recognizes that the input data is from the remote maintenance dedicated terminal device 1 based on the control code at the beginning of the input data, and removes the 1-byte control code at the beginning of the input data. The data is passed to the remote maintenance dedicated software 11 as input data.

Next, when the remote maintenance dedicated terminal device 1 receives a data output request from the remote maintenance dedicated software 11 of the minicomputer 8, the data transmission/reception control section 9 outputs the data to the remote maintenance dedicated terminal device 1. A 1-byte control code indicating that the output data exists is added to the beginning of the output data, and the output data is transmitted to the data transmission/reception control section 4 in the remote maintenance control device 2 through the input/output control device 7. Upon receiving the output data, the data transmission/reception control unit 4 determines that the data is to be output to the terminal device 1 exclusively for remote maintenance based on the 1-byte control code at the beginning of the output data, and outputs the data with the control code removed. It is transmitted as data to the remote maintenance dedicated terminal device 1 through the line control unit 3.

Further, no control code is added to data input/output to/from the system console 5. Therefore, if the first byte of input/output data is not a control code, the minicomputer 8 and the remote maintenance control device 2
The data transmission/reception control units 4 and 9 in the system console 5
Recognizes it as input/output data to and processes it.

[0018]

As explained above, the present invention provides a remote maintenance system for minicomputers, in which a data transmission/reception control section is provided in both the minicomputer and the remote maintenance control device, which are connected by an input/output control device. Since the input/output of the input/output control device is controlled, the remote maintenance terminal device and the system console can be treated as completely separate terminal devices using one input/output control device.
