Abstract
An Ethernet adapter card for automatically switching a workstation into a network is provided. The adapter card utilizes a current circuit to sense current drawn by an external communications network and a circuit for automatically switching between a card-mounted internal transceiver and the network's external transceiver whenever the external network is coupled to the workstation via an AUI port. The adapter card provides for default selection of the internal transceiver when the external communication network is disconnected from the workstation AUI port.
