一个很好用的串口类，包括同步、异步等多种调用机制。

本程序是通过串口，经由单片机控制电机转速的程序。该程序通过串口发送不同的信号，以实现控制通信。-this procedure is adopted Serial through SCM motor speed control procedures. The procedure adopted Serial send different signals to achieve control and communication.

实现了modbus RTU通讯协议的COM组件-realized Modbus RTU communication protocol COM

串口通信的东东 串口通信的东东串口通信的-Dongdong serial communications serial communications serial communications Dongdong

和基本使用BCB控制RS-232信号控制测试的源代码，初学者推荐

用于串口通信的程序,自己觉得很不错,发过来.-for serial communication procedure, feel very good, made up.

vb串口程序，写的是一个串口使用例程，对初学者有用，特别是工控类的-vb serial procedures, to write a serial port using the routines, useful for beginners, especially the industrial category

这是利用VB编写的一个通信协议程序，能实现通讯测试功能-This is the use of VB to prepare a communication protocol process, to achieve functional communication test

自己用API编写的端口通讯-Port Communication with API by myself

一个入门的程序，不错的哦。好好好学哦。我就是这样入门的哦-an entry procedures, good oh. Oh well, studious. That is the way I start oh

用VC实现的串口调试软件-with VC serial debugging software
