This is the Linux Serial Programming HOWTO. All about how to program communications with other devices / computers over a serial line under Linux. Different techniques are explained: Canonical I/O (only complete lines are transmitted/received), asyncronous I/O, and waiting for input from multiple sources.
This is the first update to the initial release of the Linux Serial Programming HOWTO. The primary purpose of this update is to change the author information and convert the document to DocBook format. In terms of technical content, very little if anything has changed at this time. Sweeping changes to the technical content aren't going to happen overnight, but I'll work on it as much as time allows.
If you've been waiting in the wings for someone to take over this HOWTO, you've gotten your wish. Please send me any and all feedback you have, it'd be very much appreciated.
All examples were tested using a i386 Linux Kernel 2.0.29.
