System and method for emulating serial port communication
First Claim
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.

Abstract
A method and system of emulating serial corn port communication. A computer processing system has computer-executable operating system instructions including first instructions that interact with a first serial device according to a predefined input/output (I/O) hardware interface. A first serial device has a receive port and a transmit port and has the predefined (I/O) hardware interface. A second serial device has a receive port and a transmit port. The transmit port of the first serial device is in serial communication with the receive port of the second serial device, and the receive port of the first serial device is in serial communication with the transmit port of the second serial device. Computer-executable instructions emulate serial communication port device communication and include instructions that transmit information over another medium in response to receive requests from the second serial device. The transmitted information includes information representative of the receive request from the second device. 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. The emulation instructions further include instructions, responsive to a communication received from the other medium, that transmit information representative of the received communication to the transmit port of the second serial device. The emulation system communicates with at least one console device. The other medium comprises a packet-based network. The other medium comprises a cell-based network. The operating system communicates directly and solely with the predefined I/O hardware interface.

8. A method of emulating serial communication port communication over an alternative transport, comprising:
-
an operating system communicating a message directly with an exposed hardware interface of a first serial communication port device;
the first serial communication port sending the message from the operating system on to a receive port of a second serial communication port device;
the second serial communication port device generating information indicative of the receipt of the message;
emulation logic, in response to the generated information, conveying a message on the alternative transport to thereby emulate serial communication port communication on the alternative transport. - View Dependent Claims (9, 10, 11, 12, 13, 14, 17, 18)
