串口编程代码 使用spcomm的 有例子事例-serial programming code used spcomm examples of instances

调用WinAPI函数进行串口通信，并且应用了多线程技术启动工作线程对串口的输入进行监听-call WinAPI serial communication functions, and uses multi-threading technology to activate the working threaded serial input eavesdropping

利用MSComm进行pc串口编程。好用-MSComm to pc using serial programming. Easy to use. . . .

GSerial是一个DOS下串口通信程序，程序结构较好，能编出用中断方式接收/发送的多串口通信程序（龚建伟曾用它编过7串口通信程序）。Turbo C++ 3.0 Dos或 Win3X/9X/ME/NT/2K的DOS环境下运行-GSerial under DOS is a serial communication program, program structure better, can be compiled out with interrupt receiving/sending of multiple serial communication program (Dan has used its seven series serial communication procedures). Turbo C 3.0 Dos Win3X/9X/ME/NT/2K or the DOS operating environment
