The complete control-thing should be done in the positioner, so the
possibility that
the dish is stopped at a wrong position is zero, but I don't know what
happens
if vdr was able to tune during dish-movement and loses the signal again? I
expect that another tuning is neccessary to show a picture again.

It's exact one command with the number of the sattelite position as
parameter....
