modbusRTU Communications with RS485

用C#语言编写串口通信程序详解，有代码有步骤(c#Serial programming steps detailed)

VC从串口读取数据并实时绘制曲线图，非常好用。(VC data from the serial port to read real-time rendering curve is very useful.)

vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)

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)

串口调试程序源代码，本例作为学习串口编程具有很好的参照作用。(Serial debugger source code, in this case as a learning serial programming with a good reference to the role.)

最新版CSerialPort类(2014年)，还包含一个旧版本,可以进行比较使用。(The latest version CSerialPort class (2014), also contains an older version. Use can be compared.)

说明：  通过CreatFile SetupComm GetCommStat等API函数来创建一个串口传输程序(CreatFile SetupComm GetCommStat such as through the API function to create a serial transfer procedure)

实现串口通信功能 基于MFC的对话框，程序简单易懂 适合初学者(Serial communication functions based on the MFC dialog box, the program is easy to understand for beginners)

VC实现和S7-200PLC的串口通信程序,很有价值哦(VC and S7-200PLC Serial Communication Program and of great value oh)
