(Step S8). Then, the CPU 50 determines whether or not a ring tone has arrived, for example, 10 times or more through the telephone matching unit 42. At the same time, it is determined whether or not the acquired caller identification information is information registered in the data storage unit 46 (step S10). Here, if it is determined that 10 or more ring tones have arrived and it is determined that the caller identification information is registered information, the remote control unit 40 is set in the hook-off state to A call loop between the remote control units 40 is set (step S12). If it is determined that the number of incoming ring tones is 10 or less, the determination process in step S10 is executed again. If the number of incoming ring tones is 10 times or less and the determination result of the caller identification information is denied, remote control from the caller to the personal computer 20 or 110, 120. Ends.

  Next, the CPU 50 controls the voice generator 48 to send a voice guidance message for password entry to the caller (step S14). This voice guidance message is sent from the telephone matching unit 42 to the remote control telephone 10 through the public switched telephone network 12.

  Next, the current state of the personal computer main body 20 or 110, 120... Detected by the on / off / reset detection unit 54 through the PCI slot 32, that is, the power on or off state of the personal computer main body 20 or 110, 120. Alternatively, the reset state is transmitted from the DTMF transmission / reception unit 52 to the remote control telephone 10 through the telephone matching unit 42 and the public switched telephone network 12 (step S15). The state of the personal computer main body 20 or 110, 120... Is displayed on the display unit of the remote control telephone 10. At the same time, the CPU 50 is notified of the power on / off state or reset state of the personal computer body 20 or 110, 120.

  Upon receiving the voice guidance message, the remote control telephone 10 inputs a password according to the voice guidance message. The input password is taken into the CPU 50 through the telephone matching unit 42 and the DTMF transmission / reception unit 52. The CPU 50 determines whether or not the password entered on the remote operation telephone 10 as the caller matches the password registered in the data storage unit 46 (step S16). If it is determined that the passwords match, the voice generator 48 is controlled so that the caller inputs a desired command to the personal computer main body 20 or 110, 120. A voice guidance message indicating this is transmitted (step S18). This voice guidance message is sent from the telephone matching unit 42 to the remote control telephone 10 through the public switched telephone network 12. Thereafter, the caller sends a command desired by the caller according to the voice guidance message and the current state of the personal computer main body 20 or 110, 120..., Such as a power-on command, a power-off command, or a reset command. Input by operating 10 push buttons or the like. The command information is sent from the public switched telephone network 12 to the DTMF transmission / reception unit 52 through the telephone matching unit 42, converted into a digital signal, and then taken into the CPU 50. Accordingly, the CPU 50 determines what command is input by the caller (step S20). If it is determined in step S16 that the passwords do not match, the process proceeds to step S28 to turn off the personal computer 20 or 110, 120.

  If it is determined in step S20 that the command input from the remote control telephone 10 is a command to turn on the personal computer main body 20, a power-on signal is output from the CPU 50 and the personal computer main body 20 or 110, 120 is output. ..

Thereafter, the CPU 50 extracts the IP address through the standard serial communication port 58 of the personal computer main body 20 or 110, 120... Connected to the serial communication port of another personal computer (step S24). In this case, a predetermined program for extracting the IP address must be installed in the data storage unit 46 of the remote control unit 40. Next, the CPU 50 selectively controls the voice generation unit 48 and the DTMF transmission / reception unit 52 so that the extracted IP address is converted into voice by the voice generation unit 48 and sent to the caller, or the DTMF transmission / reception unit 52 performs DTMF. It is converted into a signal and sent to the remote control telephone 10 (step S26). Thereafter, the process returns to step S18.

  In this case, the IP address is converted into a DTMF signal by the DTMF transmission / reception unit 52 or sent to the remote control telephone 10 as a voice message from the voice generation unit 48. The remote operation telephone 10 can be viewed by listening to the IP address by voice or by displaying the IP address on the display unit provided in the remote operation telephone 10.

If it is determined in step S20 that the command input by the caller is a command to turn off the personal computer main body 20, the CPU 50 outputs a power off signal to output the personal computer main body 20 or 110, 120,. The power is turned off (step S28). Thereafter, the process returns to step S18.
