When performing personal computer work on the PC body 1 while moving or from a destination, the power of the PDA terminal 6 is turned on. When the power is turned on, the basic control program is written from the ROM 18 to the memory 19, and the microprocessor 20 executes the basic control program.

The basic operation is displayed on the liquid crystal screen by the display control unit 17. The location to be instructed is indicated by the input pen according to the guidance on the screen display. The information on the input pen is input by the pen input control unit 15 to the pen input switching unit 22 via the input / output bus 21. When a line connection is instructed by pen input (S10 to S12 in FIG. 2; hereinafter, FIG. 2 is omitted), dialing is performed by the modem unit 12 and a connection request is made to the remote control relay device 2. After receiving the connection response from the remote control relay device 2 (S13), password verification is performed between the PDA terminal 6 and the remote control relay device 2 (S14 to S23). When the external input / output device 5 is connected when the password collation result is normal, input / output switching is performed on the external input / output device 5 by the input / output switch unit 16 (S29). Once the connection environment is set up,
Data packets are transmitted and received by the interface unit 13 (S50 to S51). External input / output device 5
Is not connected, the local PC body 1

2 is sent to the PC main body 1 through S2 (S40 to S41).

Next, the remote control relay device 2 controls whether to switch input / output of input / output information to / from the PC main body 1 from the input / output device 3 or the PDA terminal 6. When remote control is not performed, information is input and output from the input / output device 3 connected to the remote control relay device 2 (S01 to S0).
2). When performing remote control, a connection request from the PDA terminal 6 is detected (S12), and the modem unit 8 is activated. P
After the line connection with the DA terminal 6, the remote control repeater 2
Like the terminal 6, the password matching is performed by the password matching unit 11.
(S18), and returns the collation result to the PDA terminal 6 via the interface unit 9 and the modem unit 8 (S19 to S20). If the password collation result is normal, the input / output switch unit 7 is switched to the interface unit 9 in response to a switching instruction (S24) from the PDA terminal 6 (S26). However, since the display data differs depending on the model of the display 4, the display data is converted by the driver conversion unit 10 so as to match the display information data of the PDA terminal 6.

When the connection is also completed on the remote control relay device 2 side, the input / output information from the PC main body 1 is transmitted / received to / from the PDA terminal 6 by the interface unit 9 and the modem unit 8 (S40 to S41).
