串口通信例程，内含串口类，一个老外写的，我修正了一个bug：在接收数据流未完成前退出程序会导致进程驻留在内存...

提供I2C总线初始化、工作时的启始位、结束位、提供I2C总线的时钟信号，并返回在时钟电平为高期间 SDA信号线上状态。本函数可用于数据发送，也可用于数据接收-provide I2C bus initialization, the Start-end, provide the I2C bus clock signal, the clock and return to the high-level signal line during the SDA state. This function can be used to transmit data, can also be used for data reception

实现字符转换！需要在两台机子上运行，也可以把一台机子的两个com口连在一块！这样就行了！还需要一个串口调试程序，网上可以下载到！-achieve characters change! The need to run two machines, one Taiwan can the two com loom even in a mouth! So OK! Need a serial debugging procedures can be downloaded to the Internet!

本源码采用spcomm串口控件，接受数据采用线程方式，这是一个串口测试工具，可以用来做串口监听等。非常适合使用delphi开发串口程序的程序员做参考！-the source used spcomm Serial Control and accept data using threads, it is a serial testing tools can be used to do Serial wiretapping. Delphi is very suitable for the development of Serial procedures programmers refer!

实时控制，可根据需要增加或删除参数变量，随机曲线表示实例。-Real-time control, can be the addition or deletion of variable parameters, said examples of random curves.

一个好用的串口调试软件，不下载可惜了，方便你的工程开发-An easy to use serial port debugging software, not to download Unfortunately, and to facilitate the development of your project

自编的串口通信程序，支持一些简单命令-self serial communication program to support some simple orders

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
