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
