This patch causes a serial port's fd to be put into blocking mode if
FILE_FLAG_OVERLAPPED is not specified and non-blocking mode if it is.
ReadFile should block on serial ports for non-overlapped reads. The
next step is to refuse overlapped reads and writes if the file isn't
opened with FILE_FLAG_OVERLAPPED specified.
