ABSTRACT:
A wireless modem which enables user programming of radiotelephone features such as call waiting, MIN selection, and the like, without requiring a keypad interface. The wireless modem is comprised of decoder logic that determines if commands are present in a data stream from a computer. If commands are present, the decoder instructs a multiplexer to switch the modem commands to the modem subsystem and the radiotelephone feature commands to the radiotelephone subsystem. Each subsystem is comprised of a register that stores the command. The control logic in each subsystem then reads the command and acts upon it accordingly.
