基于Delphi的串口通信程序设计方法

Method of Serial Port Communication Program Design Based on Delphi

概述了串口通信在现代科技领域中的重要地位,介绍了Delphi作为一种面向对象的可视化的高级编程语言在串口通信编程中的优缺点。分析归纳了利用Delphi语言编写串口通信程序的四种方法并且简单阐述了SPCOMM在Delphi环境中作为通信控件的一些属性、方法、函数和事件。最后以实践中编写的一个惯导计算机人机交互测试程序为实例,给出了在Delphi环境中利用SPCOMM控件实现串口通信时所遇到一些常见问题的解决方法、编写串口通信程序的大体框架结构和部分代码。

Summarize the important status of serial port communication in modern science and technology arca, introduce Delphi＇s advantage and disadvantage as an object oriented visible advance programmable language in serial port communication program. Analyses the four methods using Delphi program serial port program and simply explain some attributes, methods, functions and events of SPCOMM based on Delphi. At last, using a serial port communication program as an instance,offer some methods that can solve some familiar questions in serial port communication, frame of programming serial port communication program and part of codes.
