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.
本文是为 linux 串口程序编写的 howto. 主要讨论如何在 linux 环境下，编写串口与其它计算机设备进行通讯的程序。文中所谈到的技术包括: 标准的 i/o (只具备 传送/接收 线的), 异步 i/o, 以及 等待来自多信号源输入 的程序。
本文是初始的 linux serial programming howto 的第一个升级版。主要升级了一些作者信息，把文件转换为 docbook 格式。就技术内容而言，几乎没什么大的改变。大规模的技术内容的改变是不可能一夜之间发生的，如果时间允许，我会尽量做一些工作。
如果你正在一边等着有谁来接管这份 howto,那你的心愿达成了。我会感谢你发来的任何反馈信息。
所有的示例都在 i386 linux kernel 2.0.29 下测试通过。
