Abstract
An external modem providing for the increased throughput of a serial device of a computer by de-multiplexing data over a pair of physical serial channels of the computer in a predetermined manner is disclosed. A communications port allows for communicatively coupling the computer to an external communications system, such as ISDN. A driver de-multiplexes data received from the logical serial device for transmission over the pair of physical serial channels. A controller then receives the data from the pair of serial channels for transmission over an existing communications system. Communication throughput from the computer to the existing communications system therefore exceeds the maximum throughput of a particular serial channel. The controller also is capable of receiving data from the external communications system for transmission over the pair of serial channels, the driver also capable of multiplexing the data received from the pair of serial channels for transmission over the logical serial device.
