Revises and updates the first edition of 1987. An intermediate-to-advanced reference, leaning to the advanced, about asynchronous serial communications as it is found on microcomputers. The first section presents the theoretical and practical background information required to understand the objectives of the programming section. Using the first section as a backdrop, the second section develops the programming tools to accomplish everyday serial programming chores. The programming examples are in C. A companion diskette is available. Annotation copyright Book News, Inc. Portland, Or.
If you are planning to do any serious programming with serial communications, I suggest you purchase a copy of this book. Instead of just a narrative, this book contains key charts, C code, and X modem information, informational and classical C R C circuits, frequency modulation, scratch pads, terminal information, R S 32 intimation, and on, and on, and on.
It includes an ASCII poster. I have tried mounting my copy of the ASCII poster and placing it on Wall above the CRT. The people where I took it to be dry mounted asked me if this was an eye chart.
The Bullets on the back cover include: · The ASCII character set and cover extension techniques.
· The fundamentals of asynchronous technology: baud rate, START and STOP bits, and more.
· Error-checking methods including a landmark treatment of C R C’s. · Flow-control and file-transfer protocols. · Modems: theory and practice. · The rs-232 interface from the programmer’s point of view. · Intelligent modems, including the entire Hayes smart modem family. · UART's: a detailed examination of two popular products the 8250 and the deceit Z80SIO.
This book is 655 pages long and there is not one wasted.
I love this book. I don't need it anymore, but it was fantastic when I did.
The first half is an unexpected wonderful history book about serial communications starting long before computers existed. Entertaining and informative.
The solid and well-explained second half basically got me a job I held for some years. These days we don't use modems or non-USB serial ports anymore, but when we did, this book was indispensable to me and I referred people to it all the time.
