| 摘 要： | 在VC 6．0中利用MSComm控件实现串口通信时实时性较差。系统资源利用不足。无法满足高速串口数据采集软件的编程要求．针对高速串口数据采集软件的设计要求，提出了基于多线程技术和自定义消息机制的异步串口通信的设计思想．结合串口通信的机理和多线程同步方式，分析了Win32系统下多线程异步串口通信程序的开发方法。

| Abstract: | When we use controls of MSComm in VC 6.0 to realize serial communication,the behavior of real time is poor, the application of system resources is insufficiency, so it is not satisfied with the request of high speed serial communication's acquisition system. This paper analyze the mechanism of multi-thread in serial communication, it discussed the question of thread synchronization and provides a solution . A model of high speed serial communication based on multithread is presented and realized. This program can receive and send data at the same time with high speed, which is effective, credible and has highly practicability. |
