System and adapter card for remote console emulation
First Claim
1. An adapter card (18) for providing, via network (12), emulation of a console of a first computer system (14) at a second, remotely located computer system (16) on the network, the adapter card comprising:
- a local bus (28) that interfaces to an input/output bus (20) of the first computer system when the adapter card is connected to the first computer system;
a graphics controller (22) coupled to said local bus that interacts with the first computer system to generate a representation of a console screen of the first computer system;
a network interface controller (24) coupled to said local bus and providing a connection to the network; and
a processor (26) coupled to said local bus that determines changes in the representation of the console screen of the first computer system and that transmits information about the changes to the remotely located computer system via said network interface controller and a first-in, first-out (FIFO) buffer (43) coupled to an output of said graphics controller for capturing data representing the console screen of said first computer system, and wherein said processor determines changes in the representation of the console screen by processing the data in said FIFO buffer.

Abstract
A system for providing, via a network, emulation of a console of a first computer system on a second, remotely located computer system on the network comprises an adapter card installed in the first computer system and a client program executing on the remotely located computer system. The adapter card comprises a local bus that interfaces to an input/output bus of the first computer system when the adapter card is connected to the first computer system, a graphics controller coupled to the local bus that interacts with the first computer system to generate a representation of a console screen of the first computer system, a network interface controller coupled to the local bus that provides a connection to the network, and a processor coupled to the local bus that determines changes in the representation of the console screen of the first computer system and that transmits information about the changes to the remotely located computer system via the network interface controller.
