[Com Port多串口多线程工业控制实现

Description: 由于工作关系几个月没有接触Internet了,回来发现很多朋友给我写了信,其中很多一部分都是关于串口方面出现了问题。由于在以前的工程实施过程中关于串口通讯我有时用MSCOMM控件,有时自己用WIN32 API直接操作串口。后来还试验了网络上面很流行的SerialPort类。在工业控制过程中间我对SerialPort类进行了一些简单的修改,发现这个类确实是一个非常好的东西,其中封装了操作串口复杂的一些串口操作。我们使用的时候可以直接通过它的一些简单的接口就可以完成各种外围设备的工作了。我对串口数量和程序长时间运行做了一些测试,效果都是很好的(串口扩充到了11个,运行时间是在一个项目中,到现在已经运行了1个多月没有出现问题)。 -working relationship several months without Internet access, back found many friends wrote to me, many of which are part of the serial connection is a problem. As in previous works on the process of implementing serial communications I sometimes use MSCOMM control, sometimes they used WIN32 API directly with the serial port.
