ABSTRACT:
A data communication system which enables an electronic accessory, such as a computer, to communicate data in both an analog type radiotelephone system and a digital type radiotelephone system. The data communication system first determines in which type of system it is operating and the dual mode radiotelephone (101) then uses the data signal at either the analog input port (104) or the digital input port (105), depending on the type of system.
