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)

说明：  调试使用的串口助手，程序源码，功能齐全，可以调试程序(Serial Port Assistant for Debugging, Program Source Code, Full-featured, Debugging Program)

用C#编写的串口助手，源码，并有波形显示，保存数据；自动识别串口，二进制，十进制，16进制发送；等功能。(Written in C# serial assistant, source, and waveform display, save the data automatically identify serial, binary, decimal, hexadecimal sent other functions.)

自动识别串口，一个很好用的串口模拟器 联合开发网 - pudn.com

vs2010环境下c#串口通信完整程序实例(Examples of environmental integrity program under vs2010 c# serial data transceiver)

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)

用Turbo C编写的一个串口操作小程序，能发送，接收信息；程序功能简单，过段时间再把经过修改后的版本传上来(using Turbo C serial prepared by a small operational procedures, send, receive information; Functional procedures simple, then over time, after revision line with the traditional version.)

串口通信单片机与电脑,用于学习使用，不作其它用途(Serial communication microcontroller and computer use for learning, not for other purposes)

seriport串口收发数据的测试软件，可以有效都测试终端设备是否安装成功(Seriport serial data transceiver)

说明：  台达校验码是ASCII的，VB源码。网上大部分是RTU的(Delta check code is ASCII, VB source code.Most of the Internet is RTU.)
