HANDLE hDevice, // handle to the device
DWORD dwIoControlCode, // use IOCTL_SERIAL_SET_WAIT_MASK
LPVOID lpInBuffer, // pointer to input buffer
DWORD nInBufferSize, // input buffer size
LPVOID lpOutBuffer, // pointer to output buffer
DWORD nOutBufferSize, // output buffer size
LPDWORD lpBytesReturned, // number of bytes returned
OVERLAPPED lpOverlapped // pointer to OVERLAPPED structure
);
