近，总是有人问我要串口通讯源代码，为了方便大家，我将我写的WIN32API串口通讯程序发上来，供大家下载使用（这个是我在广西的一个项目的一个源代码，其中涉及到公司的串口外围设备，我没有给出通讯规则，可能大家看程序时有很多不便请谅解）。

WIN32API通讯程序采用多线程的形式进行驱动，程序中采用多串口进行通讯，有串口数据接受和发送。其中设置、读串口、写串口功能函数全为个人所写，大家可以随意使用。 -nearly always someone asked me to serial communications source code, in order to facilitate everyone, I will I write WIN32API serial communication line with the procedures, We downloaded for use (this is the one in Guangxi project a source code, Companies involved in the serial peripheral equipment, I have not given communications rules You may see a lot of procedures inconvenience understanding). WIN32API communication procedures using multithreading in the form driven process for the multi-port serial communications, Serial data is sent and received. Which set up, reading Serial, Serial-function was all written for individuals, we can use at will.
