There will be a driver for IrDA on serial ports.  A problem is that different
adapters need to be handled slight differently when e.g. changing speed.

One way to handle serial ports is to do it all in user-land code, an alternative
is to use a different line discipline for IrDA and access it through /dev/irdaNN.
Either way, the problems above is present.
