cai yong 一个串口拓展成4个串口！(1 uart to 4)

基于vs2012的串口调试助手调试软件，简单清晰适合于初学者。(Based vs2012 serial debugging aides debugging software, is clear and simple for beginners.)

vc++制作串口调试助手，用vc6.0开发环境，一步一步教大家制作串口调试助手(vc++ production serial debugging assistant with vc6.0 development environment, step by step teach you making serial debugging assistant)

这个是非常流行的串口调试工具的VC++源代码，对于需要深入了解串口通信的朋友非常有帮助，需要的朋友可以看看。(This is a very popular tool for serial debug VC++ source code, the need for deeper understanding of serial communication very helpful friend, a friend in need can take a look at.)

该源码为平时所用的串口调试工具的源码，效果还是挺不错的(The source is usually used for serial debugging tools, source code, the effect is very good)

可以向串口发送数据，或从指定串口接收数据　VC源码-基础编程-源程序代码免费注册下载(Can send data to a serial port, or from specified serial ports receive data source-basic programming VC-source code downloaded free registration )

使用VS2013的MFC编写的一个简单Modbus RTU的单命令控制Demo，能够实现继电器的开和关(A single command control demo of a simple Modbus RTU written in MFC of VS2013 enables relay opening and closing)

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)

给出了基于MFC的can232接口的调试程序(MFC-can232 given based debugger interface)

这是MFC串口编程的具体步骤 对学串口编程有很大帮助(This is the MFC programming serial port programming of specific steps to learn of great help)
