学习C++，先学串口编程，本程序就是以串口作为编程对象，进行针对串口的数据接收与发送，内含丰富的注释，纯个人理解！(To learn C++ learn first serial programming, the program is as a programming object to the serial port for serial data reception and transmission, contains a wealth of comments, pure personal understanding!)

c++程序,对串口操作，数据对串口的收发(c++, on the serial port operation)

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)

简洁的VB串口调试程序。适合初学者学习和参考(Simple VB serial debugger. Learning and reference for beginners)

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.)

串口调试助手源码,mfc，用控件编写，包括自动发送和十六进制显示(Serial debugging assistant source)

串口调试精灵源代码,试过了，好用，自己可以在上面少量修改增加自己需要的功能。(Serial debug source code wizard, tried, and easy to use, they can increase their own minor modifications in the above functionality required.)

实例321——利用MSComm控件进行串口通信(Examples 321 use MSComm control serial communication)

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 )

说明：  RS232-c串口编程资料收集整理，有C源码实例。 (Serial programming data collected, there are C source code examples.)
