<p>PURPOSE:To attain free communications even if one is away by analyzing whether a signal is a true transmission start signal to a prescribed communication equipment on a reception side from a communication equipment on a transmission side, receiving instructions from the analysis means and supplying a power source in the communication equipment on the reception side. CONSTITUTION:When a host computer 1 originates a specific information signal, a MODEM 2 on the host side modulates the signal and transmits it to a telecommunication line 3. A MODEM 4 on a terminal side demodulates the modulated signal, and transmits it to a terminal side computer 5 and simultaneously to the analysis means 6a. It checks the coincidence of the address of the terminal side computer 5, and transmits an instruction signal that supplies a power source to an AC power source plug 6c to an output means 6b. By receiving the instruction signal, a power source is supplied to the AC power source plug 6c in the output means 6b. Thus the terminal side computer becomes conductive, and information is exchanged.</p> |
