mscomm

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)

vc++ 串口编程,用vc++编写上上位机程序 常见的几种方式以及注意事项均有介绍

串口驱动程序，可替换NT下的串口驱动程序 (Serial dirver which can replace serial driver in NT)

vc写的基于udp的串口通信简单实例 (Udp serial communication instance, a simple small program)

串口通信，对串口发出的数据进行读取和处理，进行检测(Serial communication, read and process the data sent by the serial port, and detect it.)

VC++之MFC串口,包含串口调试助手源程序 及编程详细过程 (MFC serial port)

说明：  很多下位机程序员都有这样的经历，在交付工程的时候对方要求提供源程序，而大多数下位机程序员都知道交出源程序是意味着什么，所以为了保护各位下位机程序员的合法利益.这个工具，伪装过后的源程序可以编译通过。(many lower computer programmers have the same experience that the delivery of the other works on the request source, and most of the next crew to surrender programmers are aware of what it means to the source, Therefore, in order to protect you and lower computer programmer's legitimate interests. this tool, camouflage after the source compile.)

串口调试助手VB.zip 我想大家都用过 串口调试助手， 也都期望自己能够制作出同样的通信界面； 那么这里的工具，让你如愿…… 采用VB编程，超级简单实用。(Serial debugging assistant VB.zip I would like that we have used serial debugging assistant, also expect to be able to produce the same communication interface where the tool that allows you to do so ... using VB programming, super simple and practical.)

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)

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)
