The syntax of the diseqc.conf will of course remain compatible, so that
existing setups will work unchanged.

There will just be one additional control character (presumably 'P' for
"Position"). If it is followed by a number, as in

S19.2E  11700 V  9750  t V W15 [E0 10 38 F0] W15 P1
S19.2E  99999 V 10600  t V W15 [E0 10 38 F1] W15 P1
S19.2E  11700 H  9750  t V W15 [E0 10 38 F2] W15 P1
S19.2E  99999 H 10600  t V W15 [E0 10 38 F3] W15 P1

then GotoPosition() will be called with that number. If there is no number,
GotoAngle() will be called with the satellite's longitude.

I'm also thinking of allowing something in the form of

*  11700 V  9750  t V W15 [E0 10 38 F0] W15 P
*  99999 V 10600  t V W15 [E0 10 38 F1] W15 P
*  11700 H  9750  t V W15 [E0 10 38 F2] W15 P
*  99999 H 10600  t V W15 [E0 10 38 F3] W15 P

(note the '*' instead of, e.g., 'S19.2E'), which could be a shortcut
for a (USALS) positioner that could receive any satellite (as long as it's
above the horizon).
