PC COM ports, USB virtual COM ports, and ports in embedded systems are all addressed in this updated guide to programming, interfacing, and using serial ports. Topics include using .NET’s SerialPort class for COM-port communications on PCs; upgrading existing RS-232 designs to USB or wireless networks; and creating serial networks of embedded systems and PCs. Example circuits and code provide a quick start to projects. Installation and maintenance staff will also find tips for ensuring reliable operation and problem tracking.

If you work with or need to work with RS-232, USB or RS-485, this book is a must-have reference. The subject matter of this book is heavy on the embedded side of serial communications as Jan covers .NET serial programming and explains how to completely configure a serial port on a microcontroller. Jan then goes on to tell you how to bring up an RS-485 network. Leaving no stone unturned, Jan explains how to design and deploy an embedded RS-232 network.
In addition to the discussion of traditional serial data formats and serial hardware implementations, Jan includes tips on how to use the special-function FTDI USB/Serial IC. She even explains why wires pick up noise and how to choose the right wire for the application.

Jan’s new book is a one-stop serial communications reference which includes serial connector pinouts, data format illustrations, example soource code and a multitude of schematic representations. If you need to know how to successfully deploy serial links, you need to have this book on your desk.
