BTW: also nut started complaining every 10 minutes or so about the UPS 
going away. This is also on a serial line, as is the gps.
I get stuff like:
Broadcast message from nut (Wed May  6 07:07:50 2009):

Communications with UPS myups at localhost lost

Broadcast message from nut (Wed May  6 07:07:59 2009):

Communications with UPS myups at localhost established

But the retry, after a poll interval timeout (9 seconds), is OK. So why 
did the initial poll fail? Interrupt work?
How to fix?

Where is Rodolpho?
Alan?

Kind regards,
Udo
