DOS下，异步串口通信C代码，根据具体需要可裁减

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.

232通讯 用于电脑232通讯 可以发送和接受数据-232通讯

RCC底层通信程序 包含协议和测试报告-RCC SerialPort

SPI读写，通过ＲＳ２３２协议传输！弹片机读写！-err

PC_COM串口通信-PC_COM Serial Communication

用于实现上位机与下位机通信功能。用于串口通信。-For implementation with the lower PC communication function. For serial communication.

利用MSComm进行pc串口编程。好用-MSComm to pc using serial programming. Easy to use. . . .

串口编程调试精灵，VB实现，绝对经典。可以任意改动。保你赞不绝口。-Serial Programming Debugging genies, VB, absolute classic. Can be arbitrarily changed. You full of praise.

Delphi是一种具有功能强大、简便易用和代码执行速度快等优点的可视化快速应用开发工具，它在构架企业信息系统方面发挥着越来越重要的作用，许多程序员愿意选择 Delphi作为开发工具编制各种应用程序。但是，美中不足之处是 Delphi没有自带的串口通信控件，在它的帮助文档里也没有提及串口通信，这就给编制通信程序的开发人员带来许多不便-with Delphi is a powerful, easy-to-use and faster code execution advantages of visual rapid application development tool, the framework for enterprise information systems are playing an increasingly important role, many programmers choose to Delphi as a development tool preparation of the various applications. However, inadequate as it is not Delphi onboard Serial Communication Control, in its help files contain no mention of serial communication, which gives the procedures for the preparation of communications developers bring a lot of inconvenience

本程序调用了微软自带的mscomm控件，实现com口的数据接收，读者可自行添加发送数据功能。内附mscomm.ocx控件及其注册方法，本程序是用的静态链接库，为的是能在没有vc库的机器上也可以运行，所以个头大了点。-Microsoft"s own mscomm controls, I realize com data reception, readers can add their own functions to send data. Enclosing mscomm.ocx control and registration method, the procedure is used in the static link library, for the in the absence of vc for the machine can also run, giving the larger point.
