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

连接串口通讯程序，采用EVB书写模块，MScomm控件-Connect the serial communication program, using EVB writing module, MScomm control

可以实现HDLC帧结构中的添零功能，使得信息部分不会和HDLC帧头部分混淆。-can insert zero to the hdlc frame,

这是我自己写的关于串口通讯的小程序,适于两台PC机之间通过(交叉串口线)串口通讯.可以(自动或手动)发送数据、接收数据、保存数据。是调试串口和初步学习串口编程的好例子。其中还用到了典型的串口类，对于从事串口编程者有一定的借鉴作用。 -that I write on small serial communication procedures, suitable for two between the PC (cross-Serial Line) serial communications. May (automatically or manually) to send data, receive data, the data is preserved. Serial debugging is a preliminary study and Serial Programming good example. It also uses the typical serial category, for those engaged in serial programming is useful role.
