Can be remotely controlled in the same state as when directly connected to the personal computer 8 to be maintained, as if operating a personal computer on a desk. Therefore, a technician with advanced knowledge Not only the operation after the maintenance personal computer 8 is started, but also the observation of the start process and the change of the start method, the setting of the communication device and the setting of the communication protocol can be performed. In addition, accurate diagnosis can be performed even when the operating system does not start properly or when a serious trouble such as a hardware trouble occurs. Therefore, maintenance work (maintenance) such as inspection and repair of the personal computer 8 to be maintained.
Can be performed efficiently by a small number of engineers.

A monitor input terminal 32, a monitor output terminal 33, a keyboard input terminal 35, and a keyboard output terminal 3
6. By adapting the terminal specifications such as the mouse input terminal 37 and the mouse output terminal 38 to those of the personal computer 8 to be maintained, any personal computer can be supported. Furthermore, it is possible to correspond to all models, operating systems, and software without depending on the type of personal computer, the operating system and the type and version of software. In addition, it is possible to deal with the maintenance target 2 in any location as long as the telephone can be reached.

FIGS. 1 to 3 show a case where a general analog telephone line is used as the external line B and the communication means 17 is a modem, but the external line B is a digital line and the communication means 17 is a digital line. It is also preferable to use a circuit for digital communication. In addition to the method in which service personnel bring the host module 9 to the maintenance target 2 when a trouble occurs,
The host module 9 may always be placed on the maintenance side 2 and a user may make a predetermined connection by himself / herself when a trouble occurs, and further contact the remote operation side 1 to perform a remote diagnosis.

In some cases, a personal computer may be used as the remote control means 3. In this case, the operation signal converting means 15 and the monitor display signal reconstructing means 16 are composed of personal computer hardware and software, and the mouse operation signal M and the keyboard operation signal K are converted into the remote operation signal R by the personal computer. Then, the remote control signal R is sent to the host module 9 via the external line B, and the communication monitor signal C from the host module 9 is returned to the monitor display signal A by a personal computer to be displayed on the monitor 6. Good.
