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

串行通信的（源代码）做maxplusII

VB 5.0/6.0的MSComm通信控件提供了一系列标准通信命令的接 口，它允许建立串口连接，可以连接到其他通信设备（如Modem）、 还可以发送命令、进行数据交换以及监视和响应在通信过程中可能 发生的各种错误和事件，从而可以用它创建全双工的、事件驱动 的、高效实用的通信程序。-VB 5.0/6.0 the MSComm control communications for a series of standard communication interface orders, which allow for the establishment of serial link can be connected to other communications equipment (such as modem), and also can send orders, the exchange of information and surveillance and response in the communication process may mistakes that occurred in the incident, which can be used to create full-duplex, event-driven, highly effective and practical communication program.

采用verilog编写的串口通信程序，采用了状态机设计！程序简单，消耗资源少-Serial communication written by verilog hdl. It is designed with FSM. The program is simple,and consume resource is few.
