[En-Nut-Discussion] Bug in half duplex mode

[Harald Kipp]

The compile option (or Configurator settings) only includes the
required code for USART_MF_HALFDUPLEX. This way applications,
which don't need this special flow control are tinier and faster.

It is still required though to set USART_MF_HALFDUPLEX. If the
compile option doesn't support it, _ioctl() will return -1.

You're welcome.
