A method and apparatus for multi-protocol LAN support, which is applicable to
Ethernet,
Token-Ring, and Asynchronous Transfer Mode (ATM) protocols. The LAN support is
located at a workstation and provides for automatic determination of the LAN protocol
type and speed. A common adapter card is provided for use in the workstation to
interface the workstation to any of the LANs of interest. A four-step sequential
process is taught for determining the protocol type and speed.
