VC6.0MFC

串口调试工具，包含自动计算MODBUS crc校验码，是工具非源码(tiaoshi gongju)

MFC串口通信，可以自动检测COM口，包括发送和接收(MFC serial communication, can automatically detect the COM port, including sending and receiving)

上位机串口通信程序带电机控制程序界面(PC serial communication program with motor control programming interfaces.)

VB环境下简单的串口测试程序，测试两台主机通过串口是否能够实现数据传送，可以传送数字、字符串及汉字。(VB environment, a simple serial test program, test whether two hosts can be achieved through the serial data transfer, can send numbers, strings and characters.)

串口调试程序源代码，本例作为学习串口编程具有很好的参照作用。(Serial debugger source code, in this case as a learning serial programming with a good reference to the role.)

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.)

VC++简单而强大的多线程串口编程工具,该CSerialPort类封装了串口通信的基本 数据和方法(VC simple and powerful multithreaded serial programming tools, the CSerialPort type of serial communications package of basic data and methods)

485通讯接口模块的编程应用，监控显示，检测报警显示，上下值的设置输入输出的结构(485 Communications Interface Module programming applications, monitor display, alarm detection showed that the whole value of the structure of input and output settings)

标准串口win32接口函数,通过这些微软提供的串口接口函数可以实现对串口的读写操作(standard serial port debug source code)

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)
