// create the file port reference to specified serial port
m_hCommDev = ::CreateFile("COM1", // string of serial port device's name
                          GENERIC_READ|GENERIC_WRITE, // access mode
                          0, // MUST! no Share, exclusive access
                          NULL, // no security attribute
                          OPEN_EXISTING, // MUST! refered device must exist
                          FILE_ATTRIBUTE_NORMAL, // device attributes
                          NULL); // MUST! no copy...// read from serial port
::ReadFile(m_hCommDev, pbyBlock, dwLength, &dwRealRead, NULL);// write to serial port
::WriteFile(m_hCommDev, pbyBlock, dwLength, &dwRealWrite, NULL);...// release the reference to serial port
::CloseHandle(m_hCommDev);
