ABSTRACT:
A wireless data communication system using a microphone/headphone jack of a portable phone. The system may be constructed with a computer modem; a microphone jack and a headphone jack of a portable computer; a portable phone having said microphone/headphone jack; and an interface module which transmits signals by electrically connecting said computer modem and said microphone/headphone jack of said portable phone. A dedicated cable for interfacing the modem and the portable phone is unnecessary, a private protocol for wireless communication is unnecessary, and the private protocol does not need to be previously written into a random access memory when the data of the portable computer is transmitted/received by wireless using the portable phone. The interface module circuit between the computer modem and the portable phone is simplified, by using less cables, and an existing jack may be used for coupling the modem and the portable telephone.
