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.)

利用面向对象的C++语言的MFC编写的串口通信程序(The use of object-oriented language C++ MFC prepared by the serial communication program)

说明：  Wincc使用MSComm控件串口通讯，VB中发送十六进制数据(Wincc uses MSComm control to communicate through serial port and sends hexadecimal data in VB)

初始化RTCM控制，并且把文件或者串口数据转输出成RTCM格式(RTCM control initialization, and the output files or serial data transfer format to RTCM)

vc_串口通讯，介绍了如何用VC实现串口通信的原理和源程序(vc_ serial communication, describes how to use the VC to achieve the principle and source of serial communication)

MFC串口通信，可以自动检测COM口，包括发送和接收(MFC serial communication, can automatically detect the COM port, including sending and receiving)

利用max232，实现51单片机和电脑的通信，使得电脑发一个数据在单片机上用流水灯显示。(Use max232, achieving 51 SCM and PC communications, making the computer sends a data on a single chip with a water light show.)

该程序用MFC实现串口通信，包括串口通信的整个过程，和各种参数的设置(MFC realize the program with serial communication, including the serial communication of the whole process, and various parameters set)

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)
