I guess now you know why I never even touched that "motor" topic ;-)

I just wanted to add a simple way by which people who don't have
a setup where every DVB-S card can receive every sat position (by means
of (cascaded) multiswitches) can fine tune their diseqc.conf. There was
absolutely no intention to even think about this whole motor complexity.
That's way too complicated for my taste.
