modbusRTU Communications with RS485

国外经典的TCP转串口的程序,VC++编写,有较强的参考价值(Foreign classic TCP to serial program, VC++ write, there is a strong reference value)

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.)

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)

这是一个简单的VS2010之MFC串口编程教程，它可以指导初学者学习MFC简单入门编程(This is a simple tutorial serial programming MFC VS2010 it, it can be a simple guide for beginners to learn MFC introductory programming)

说明：  我所见过用VC写的最好的串口类，具有模拟单片机中断传输的方式，避免了查询传输CPU损耗和接收超时(I have ever seen VC was the best serial category, with simulation SCM interruption of transmission, so that the CPU for transmission and reception of overtime loss)

Visual c++实践与提高——串口通信与工程应用篇10源代码(Visual c++ practice and improve- serial communication and project source code (Application) 10)

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)

此程序实现了对串口输入的ADC数据和温度数据的实时曲线图显示。(This program realizes the serial input of the ADC data and temperature data in real-time graph display.)
