ABSTRACT:
A data communication interface for interfacing between a digital radio telephone and computer includes a first protocol converter for converting forward channel data from the telephone into a form usable by the computer and a second protocol converter for converting reverse channel data from the computer into a form usable by the telephone. The digital telephone produces a plurality of status signals indicating the operating states of the telephone. The interface receives each status signal from the telephone and stores it in a status memory. When a command signal is received from the computer, the interface makes a search through the status memory for one corresponding to the received command signal. The detected status signal is applied to the computer and displayed.
