Abstract:
1. A circuit for connecting a radio frequency transceiver to a computer, comprising a first interface for connection to transmit, receive and control terminals of a radio frequency transceiver; a second interface connected to said first interface for connecting a transmit terminal of the radio frequency transceiver to an audio output terminal of a computer, and connecting a receive terminal of the radio frequency transceiver to an audio input terminal of the computer; a third interface connected to said first interface for connecting a control terminal of the radio frequency transceiver to a serial port of the computer; and a switching circuit for selectively providing a voltage signal to said control terminal of said radio frequency transceiver to, when said third interface receives a control signal from said serial port of the computer, activate and control said transmit terminal of said radio frequency transceiver to transmit an audio signal received from said computer to at least one other radio frequency transceiver.
