ABSTRACT:
A system, apparatus, and method for emulating the operation of a peripheral device of a computer. An adapter for communicating keyboard data to a computer via a data link and for communicating display data from the computer to an external device. The adapter eliminates the need for the peripheral device to be directly connected to the computer by enabling the computer to operate without the peripheral device while still receiving or generating the data normally processed by the peripheral device. The adapter presents itself to the computer as if the adapter were the emulated peripheral device. Thus, the operation of the adapter is transparent to the computer. A remote user can access the computer, via the adapter, by communicating keyboard data generated by the user on a keyboard at a remote location. The adapter communicates display data to the user at the remote location, so that the user can monitor the operation and output of the computer. The adapter provides access to the remote user at substantially all times that the computer is operative, including the time immediately following start-up of the computer. A method is also provided for enabling a computer to process keyboard data without having a keyboard directly connected to the computer. The method also enables the computer to transmit display data to an external device at substantially all times that the computer is operative, including the time immediately following start-up of the computer.
