Abstract

A technique is described whereby a programmable communications processor (PCP) is interfaced to a host processing system so as to increase the flexibility and versatility of systems requiring compatibility with the many communications protocols, such as SDLC, HDLC, BISYNC, ASYNC, ADCCP, etc. The PCP is particularly useful in the design and development of microprocessor systems requiring the capability to interface with different communications protocols. Also, through the use of a PCP, it is possible to implement gateways, i.e., the ability to enter communications with one protocol and exit with another. In addition, the PCP is able to be implemented into complete known architectures, such as system network architecture (SNA).
