PROBLEM TO BE SOLVED: To provide a computer I/O subsystem for providing communication and control between a computer and external audio and telephone devices. SOLUTION: Data to and from multiple computer I/O ports and data to and from multiple external devices are all merged for communication over a single time-domain-multiplexed full-duplex serial bus. A telephone circuit is designed as an option. When the telephone circuit is installed, the serial bus is automatically reconfigured to accommodate the additional data and control information. The telephone circuit transparently merges serial telephone data and serial audio data. COPYRIGHT: (C)2006,JPO&NCIPI
