1. In a computer processing system having computer-executable operating system instructions including instructions that interact with a first serial device according to a predefined input/output (I/O) hardware interface, a serial communication port emulation system comprising:

  • a first serial device having a receive port and a transmit port and having the predefined (I/O) hardware interface;

    a second serial device having a receive port and a transmit port, the transmit port of the first serial device being in serial communication with the receive port of the second serial device, and the receive port of the first serial device being in serial communication with the transmit port of the second serial device;

    computer-executable instructions to emulate serial communication port device communication, the emulation instructions including instructions that transmit information over another medium in response to receive requests from the second serial device, the transmitted information including information representative of the receive request from the second device; and

    whereby transmissions to the first serial device by the operating system instructions are transmitted over the other medium and serial communication port device communication is thereby emulated over the other medium.
