windows CE下面的简单的串口调试工具

//////////////////////////////////////////////////////////////////////
// CEComm.h: interface for the CCEComm class.
//////////////////////////////////////////////////////////////////////
//
//使用时利用该类实例化一对象，首先定义一个静态私有函数作为回调函数初始化
//m_OnSeriesRead成员变量，然后打开串口，发送时调用WritePort方法，读取自动完成，
//SetSeriesTimeouts方法用于设置串口读取写超时，结束时调用ClosePort方法
//
//example:
//
//CCEComm m_CEComm; //定义串口类
//
//static void CLASS::OnSeriesRead(CWnd* pWnd,BYTE* buf,int bufLen); //定义读串口回调函数
//{
// 	 CDlg *pDlg = (CDlg *)pWnd;
//	 CEdit * pEdit = (CEdit*)pDlg->GetDlgItem(IDC_EDIT);
//
//   CString strRecv = (char*)buf;
//   CString strOld;
//	 pEdit->GetWindowText(strOld);
//	 pEdit->SetWindowText(strOld + strRecv);
//
//   delete[] buf;
//}
//
//m_CEComm.m_OnSeriesRead = OnSeriesRead;
//
