Abstract
An improved apparatus and method for isolating faults in a complex communications network such as a collision-detection network. A wrap plug connected to a communications adapter of a computer system simulates multiple functions of the network environment, rather than a single, hardwired function. A method performs a comprehensive yet convenient diagnostic test of multiple functions of the adapter while a terminal is disconnected from the network.
