Abstract
Communication between a personal computer and an electronic organizer is conducted through the audio input port and the audio output port of the personal computer. The communication interface device of this invention comprises: an output line to be connected with an electronic organizer and the audio input port of the personal computer; an input line to be connected with an electronic organizer and the audio output port of the personal computer; a voltage regulator to regulate voltages of said output line and said input line; and a voltage detector to detect voltage of the audio output port of the personal computer and the input port of the personal computer. The interface device generates control signals to the personal computer and the electronic organizer to enable the communication therebetween when both are ready to communicate.
