Cannon DE9F Serial Connector

This book explains different aspects of serial data communication. Serial data communications is the foundation for most forms of data communications used with modern computing devices. The focus of the articles in this book will be around the implementation of RS-232 (aka RS-232C, aka V.24, aka EIA-232D, etc.) based serial data communication and will explore a wide range of implementations and uses for serial data transfer.

Resources

See Subject:Computer engineering for other kinds of low-level serial interface hardware that typically have the same high-level programming interface as RS-232 (RS-422, RS-423, RS-449, RS-485, MIL-STD-188, Universal Serial Bus (USB), etc.) and hardware that happens to be serial (Serial ATA, Wifi, Ethernet, etc), although it usually uses a very different high-level protocol.
