SCOMMV23

串口通信处理的多个线程需要协调运行，一个线程必须等待另一线程结束才能开始，在处理一个线程的同时必须把其余待处理的线程挂起等待，以减少其余待处理线程对CPU的资源占用，正处理的线程一旦处理结束则通过线程间的通信发出信号来击活被挂起的线程中的一个线程进入处理。(Serial communication processing necessary to coordinate multiple threads running, a thread must wait until the end of the beginning of another thread in a thread at the same time deal with the need to deal with the rest of the thread to be suspended waiting for in order to reduce the remaining lines to be processed way of CPU resources occupation, is the thread once the deal by the end of treatment inter-thread communication signal to hit live thread was hang a thread into the handle.)

Qt写的RS232串口程序源码,需要者收了吧(RS232 by Qt)

基于Visual C++串口与下位机通信(Based on Visual C++ serial PC program to communicate with the microcontroller)

串口调试：这还是个初步的！如果你有兴趣还可以自己再改！如果还有更好的请联系我(serial debugger : This is still preliminary. If you are interested in then they can change! If there is a better contact I)

实现串口通信的编程，关于类以及继承的一些使用方法，新手可以参考。(Serial communication programming, use classes and inheritance, the novice can refer to.)

linux下的串口通讯代码，方便修改以实现多种串口通讯功能(under linux serial communication code to facilitate modified to achieve a variety of serial communication functions)

实现串行通讯的相关API函数 API函数不仅提供了打开和读写通讯端口的操作方法，还提供了名目繁多的函数以支持对串行通讯的各种操作。 函数名 作用 CreateFile 打开串口 GetCommState 检测串口设置 SetCommState 设置串口 BuilderCommDCB 用字符串中的值来填充设备控制块 GetCommTimeouts 检测通信超时设置 SetCommTimeouts 设置通信超时参数 SetCommMask 设定被监控事件 WaitCommEvent 等待被监控事件发生 WaitForMultipleObjects 等待多个被监测对象的结果 WriteFile 发送数据 ReadFile 接收数据 GetOverlappedResult 返回最后重叠（异步）操作结果 PurgeComm 清空串口缓冲区,退出所有相关操作 ClearCommError 更新串口状态结构体,并清除所有串口硬件错误 CloseHandle 关闭串行口()

C#写的控制串口继电器模块的代码，通过发送指令来控制多路串口继电器的开关。(Serial port control relay module C# to write the code, switch by sending commands to control multiple serial relay.)

这是串口调试助手，可以显示，并带有图像显示(This is a serial debugging assistant, you can display, and with image display)
