说明：  串口通信高级编程提供了一个能够进行串口通信的类，能够方便地进行各种数据通信。 由于本程序设计到硬件编程，因此，如果读者的串口通信设备 没有连接好，可能会有问题 (Serial communication provides a high-level programming to carry out the type of serial communication, the ability to easily carry out a variety of data communications. Since the hardware design to programming, so if the reader' s serial communications equipment is not connected well, there may be some problems)

RS-232 通信调试程序，初学者适应。(RS-232 communications debugger, beginners to adapt.)

串口调试助手的源码,自己编写，界面与当前流行的串口调试工具基本相同。该工具使用方便，而且可以自定义串口速率，由状态显示内容(serial debugging aids source, their preparation, interface with the popular serial debugging tools basically the same. The tool is easy to use, but can define serial rate, as indicated by the state)

基于labwindows/cvi的串口通信的实现，希望对有需要的朋友提高参考(Based on labwindows/cvi Serial Communication, in the hope that there is a need to increase the references friends)

一个简明的串口通讯例子(a simple and clear example for serial port communication)

基于CVI2010的串口编程 使用C++ 适合初学者学习(Based on CVI2010 serial port programming using c++ for beginners to learn)

485多机通讯的连接方式，主要有总线方式、星形方式等(connection of multi pc communication with 485)

PLC程序，结合VB通信实现两轴运动带减速功能(PLC programming, communication with VB to achieve two-axis motion with deceleration )

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()
