Yet again, sorry for the delay - I hope the UPS is still alive.

Before I merge it (well.. provided that it works..), I'd like to know
a couple of things more:
1. does the load.off command ('S00R0000') work?
2. does the 'C' command (mapped as shutdown.stop and load.on) turn the
load on if executed while the ups.delay.start time elapses after
having fired a shutdown.return?
3. (OK, I lied - 3 things more) does the shutdown.stayoff command
('SnR0000') work?

Thanks for your patience, Charles.
