Protocol selesction in serial data link communications

Includes bibliographical references (pages 121-123)Serial data link communications are a growing part of the computer, electronics, and telecommunications industries. A multitude of protocols are available whose purpose is to regulate serial data link communications. A need exists for the systems designer to be able to select a protocol for use in a particular serial data communications environment. There are two areas which must be evaluated prior to choosing a protocol; the characteristics of the transmission medium, and the system requirements. The necessary features of a protocol to fit the particular requirements can then be selected. These considerations are discussed. Several standard and non-standard protocols are tabulated for reference and as examples of the implementation of various features of protocols. The tools are provided to generate a protocol for a unique application if an available one is inadequate. Two examples of the protocol selection process are presented
