【摘要】 Windows CE.NET 4 .2是面向移动计算和嵌入式应用的嵌入式操作系统,特别为有限的硬件资源设计了多线程、多任务和完全优先的操作系统环境,并具有强大通信能力,RS 2 32串行通信是Windows CE.NET 4 .2支持的最基本的通信方式。介绍了在Windows CE.NET4 .2下实现RS2 32串口通信的方法和过程,包括如何打开、配置、读写、关闭串口和使用多线程来实现类似的异步串口通信,深入讨论了正确实现通信的几个关键问题。更多还原

【Abstract】 Windows CE.NET 4.2 is an operation system for mobile computing and embedded application. It designs a multithread, multitask and full priority operating system environment for limited resources specially, and it enables powerful communicate ability. RS 232 serial communication is the most basic communication mode supported by Windows CE.NET 4.2. This paper introduces the method and process of RS 232 serial communication in Windows CE.NET 4.2 including how to open, configure, read, write and close the port, and how to realize asynchronous serial port communication by means of multithread, and discusses several key techniques to realize communication rightly.更多还原
