DELPHI 6.0中用TApdComPort实现串行通信

串行通信是计算机与其他仪器设备进行数据交换的一种重要方法，如果没有仪器间的相互通信，很多测试和控制工作就无法进行，要实现PC机的串行通信通常有以下几种方法，利用嵌入式汇编语言编写程序，利用Windows提供的API函数完成与硬件接口的通信，利用第三方串口通信控件来实现等，介绍了在Delphi6．0开发环境下，用TApdComPort控件来实现一台PC机与多台单片机之间的串行通信，并提出了多线程设计方法，同时对通信程序作了详细的说明。

Realization of serial communication with TApdComPort in Delphi 6.0

Serial communication is an important way for computers to exchange data with other instruments. Without the mutual communication among instruments,many of tests and control operations cannot be carried out. To accomplish the serial communication of the PC, generally there are several ways as follow: to make use of embedded assemble language to write programs; to make use of Windows API to communicate with hardware ; make use of the third part serial communication components to realize data exchange etc. This paper introduces serial communication between PC and single-chip microcomputers with TApdComPort component based on Delphi 6.0 developing environment.And presents a novel design method of multi-threads; and it also expounds communication program.
