ABSTRACT:
A portable radiotelephone is disclosed in which an associated logic unit communicates via a data bus with an internal keypad and display and a detachable external keypad and display. Capability is provided for detecting the presence of the external keypad on the data bus and, in response to the detection, the information which would normally be communicated between the logic unit and the internal keypad and display is diverted to the external keypad and display. When the external keypad is detached from the data bus, communications between the logic unit and the internal keypad and display is reestablished.
