Abstract
A modem normally adapted for use on the PSTN communicates with a radio transceiver, typically a cellular telephone via an interface. The interface is coupled to the modem to communicate audible frequency computer data, control signals and status signals. The interface converts the audio-frequency control signals from the modem into binary signals for the radio transceiver and converts status signals from the radio transceiver to audible-frequency control signals detectable by the modem.
