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)

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

用VB编写的FX系列PLC通信动态链接库,用户只需调用API函数就可以简单的实现串口通讯(VB prepared by the FX series PLC communication dynamic link library, Users only need to call API functions can be achieved by a simple serial communications)

一个功能比较全面的串口调试工具。你值得拥有。(A more comprehensive functional serial debugging tools. You deserve. )

利用C语言实现RS232串口上下位机通信的设计(Using C language to realize RS232 serial port communication up and down a machine design )

该源码为平时所用的串口调试工具的源码，效果还是挺不错的(The source is usually used for serial debugging tools, source code, the effect is very good)

多线程串口类及其使用方法，包含完整的CSerialPort类及其使用方法。(A communication class for 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.)

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 )

使用VC.NET编写串口通信程序，是很好的串口调试软件(Use VC.NET write serial communication program is a very good serial debugging software)
