I'm testing it on hotbird. While on many transponders it seems to work 
fine, on others after 20 seconds I don't get an end of scan from pat.c, 
while I get and end of scan almost immediately from sdt.c. This occurs 
mainly on sky transponders (according to lyngsat.com, e.g. 12418V, 
12341V, 12616H, etc., while I was writing this 12713V and 12731H, also 
from sky, did work fine) but also on some others. Maybe there's 
something else to check, or maybe the pmt data is really taking more 
than 20 seconds.
Btw, this isn't going to be much faster than a timed wait: some 
transponders are taking a few seconds, but other are taking more than 10 
seconds. I hope it is more accurate though.
