Data communications for microcomputers : with practical applications and experiments
Elizabeth A. Nicholas, Joseph C. Nichols, Keith R. Musson · McGraw-Hill eBooks · 1982
Owners of microcomputers must often bear most of the responsibility for maintaining and enhancing their own systems. This easy-to-understand, easy-to-follow guide provides the basic principles and practical guidance needed to implement the hardware and software necessary to handle some common data communications problems that arise in a microcomputer-based environment. Particular emphasis is given to troubleshooting and solving problems in communications between CPUs, terminals, and printers in a typical microcomputer system, as well as to remote communications between those components via the public-switched telephone network. A series of experiments provides you with guidance in fabricating and testing interface circuits, cables, and diagnostic tools for use with any computer system, as well as in developing real-time software for use with Z80-based microcomputers.
