// 版本: 1.0
// 本程序建立一個用于串口通訊的控件ApexComm；
// 它使用線程類來實現實際的讀串口和寫串口；
// 用戶可以通過調用方法WritePort 向串口寫數據；
// 通過觸發的OnReceiveData 事件來讀取串口中的數據；
// 通過各屬性來設置串口參數；(例如波特率，端口等)
// 通過OpenPort來啟動串口通訊；
// 通過ClosePort來關閉串口通訊；
// 下面是程序中用到的用于線程讀寫的消息常量
///////////////////////////////////////////////////////////////
// 注:由于涉及串口通訊,要求系統必須同時響應串口事件和用戶輸入,
//    所以該處使用多線程來實現
