/*SerialPort中串口数据的读取与写入有较大的不同。由于串口不知道数据何时到达，因此有两种方法可以实现串口数据的读取。一、线程实时读串口；二、事件触发方式实现。由于线程实时读串口的效率不是十分高效，因此比较好的方法是事件触发的方式。在SerialPort类中有DataReceived事件，当串口的读缓存有数据到达时则触发DataReceived事件，其中SerialPort.Recei

通常，在C#中实现串口通信，我们有四种方法：第一：通过MSCOMM控件这是最简单的，最方便的方法。可功能上很难做到控制自如，同时这个控件并不是系统本身所带，所以还得注册，不在本文讨论范围。可以访问http://www.devhood.com/tutorials/tutorial_details.aspx?tutorial_id=320 ，一个国外网友的写的教程，作者很热心，我曾有发邮件给他，很快
