  • Interface for switching plurality of pin contacts to transmit data line and plurality of pin contacts to receive data line to interface with serial controller
    Patent number: 5701515
    Abstract: An analog interface for a PC module and an electronic device which communicate through a standard 68-pin PC card digital interface. The PC module includes a cellular phone radio and an analog modem that provides cellular communication capabilities to both a notebook computer and a telephone handset that includes a PC card slot. The PC module and the notebook computer have modified the standard 68-pin PC card interface, while remaining compliant with the standard interface, to enable voice applications in the notebook computer. The PC card interface is modified by reassigning pin assignments on the 68-pin connector through the use of a switch and audio lines in both the notebook computer and in the PC module.
