使用Win32创建串口通讯程序源代码：本文的目的是介绍如何在Win32中处理串口。串口通讯可以通过多种技术实现，例如：ActiveX,I/O存取和文件操作。本文介绍Win32平台下通过文件操作技术使用串口。程序员可以使用 Microsoft Visual C++ veRSion 6.0所提供的kernel32.lib。在Microsoft Windows(2000,Me,XP and 95/98)中，串口作为文件处理。因此可以通过Windows文件创建函数打开串口。文章不仅介绍了串口通讯，也介绍了在串口通讯应用程序中实现多任务，多任务可以使串口通讯应用程序在同一时间处理更多的任务，例如：读数据任务，发送数据任务，GUI任务等。

Keil C251设计软件V3.11(4k代码限制） keil c251 v3.11 demo版的安装说明：安装方法是先将V3.11安装程序用winzip解压缩到某个目录下。（不要直接点击setup.exe安装），比如解压缩到c:\c251然后执行c:\c251\setup\setup.exe 安装程序，这个程序会让你选择安装Eval veRSion版还是Full veRSion版，选择Eval veRSion版进行安装 安装好之后就可以使用，但有代码大小的限制。需要无限制的版本，请购买正版软件。 C251是intel公司的16位单片机，指令兼容51的单片机。8位单片机风靡了20年，下一个20年应该是16位单片机的世界。
