A microprocessor-controlled interface for data transmission

This paper describes how a microcomputer unit has been used to interface a serial data link to a communications processor. In the application considered, the communications processor is operating as a packet-switch in a store-and-forward data communications network. The use of software logic permits the interfacing of a serial data link to equipment for different applications. Estimates of the performance of the unit using a currently available microcomputer system are presented.
