The microcomputer 50 determines whether the ring tone is provided more than ten times, for example, a set number of times through the telephone matching unit 42 (step 10).

As a result of the determination in step 10, the microcomputer 50 sets up a call path when 10 or more ring tones are provided (step 12).

The microcomputer 50 controls the voice generator 48 to send a voice guide for inputting a password to the caller (step 14).

The microcomputer 50 determines whether the password input by the caller is correct (step 16).

As a result of the determination in step 16, the microcomputer 50 controls the voice generator 48 to send a voice to the caller to input a desired command (step 18). At this time, the caller inputs a predetermined command together with an ID for selecting any one of the plurality of PC main bodies 20, 110, 120, ....

The microcomputer 50 determines the ID and command of the specific PC that the caller inputs (step 20).

As a result of the determination of step 20, the microcomputer 50 turns on the power of the PC having a specific ID if the command inputted by the caller is the power of the PC (step 22). At this time, the PC having a specific ID is normally powered up with power.

If the PC having a specific ID is the PC main body 20, the microcomputer 50 extracts an IP address through the serial communication port 58 of the PC standard connected to the serial communication port of the PC (step 24). At this time, a predetermined program for extracting the IP address should be installed in the PC.

The microcomputer 50 selectively controls the voice generator 48 and the DTMF transceiver 52 to transmit the extracted IP address to the caller as a voice or DTMF signal and returns to step 18 (step 26). In this case, the IP address may be simultaneously transmitted to the caller as a voice and DTMF signal so that the caller can listen to the voice or view it through a display window provided in his or her phone.

As a result of the determination of step 20, the microcomputer 50 turns off the power of the PC and returns to step 18 if the command inputted by the caller is the PC power off (step 28). At this time, when the microcomputer 50 determines that the command inputted by the sender is the PC power off, the microcomputer 50 may maintain the current state of power and end the current algorithm.

As a result of the determination of step 20, if the command input by the sender is other than the PC power on / off command, the microcomputer 50 performs the corresponding command and returns to step 18 (step 30).

The microcomputer 50 may control the voice generator 48 whenever the caller executes the command, and may transmit the command execution to the caller by voice. The microcomputer 50 controls the on / off of communication devices respectively connected to a plurality of PC bodies 110, 120, ... according to a specific command of the caller, and checks each state to report to the caller.
