提供串口通讯参数设置接口

// 版本: 1.0
// 本程序建立一个用于串口通讯的控件ApexComm；
// 它使用线程类来实现实际的读串口和写串口；
// 用户可以通过调用方法WritePort 向串口写数据；
// 通过触发的OnReceiveData 事件来读取串口中的数据；
// 通过各属性来设置串口参数；(例如波特率，端口等)
// 通过OpenPort来启动串口通讯；
// 通过ClosePort来关闭串口通讯；
// 下面是程序中用到的用于线程读写的消息常量
///////////////////////////////////////////////////////////////
// 注:由于涉及串口通讯,要求系统必须同时响应串口事件和用户输入,
//    所以该处使用多线程来实现
