Good to know, thanks Larry. But since this ups isn't big enough to handle
the other 2 much hungrier wintel systems, I see no reason to have it
talk to the other 2 wintels who by the time the shutdown command has
arrived, which it probably won't anyway because the lights are off
including the 8 port switch that brings the shutdown cmnd and have been
for 2 secs then. So this will be only for the pi, to bridge the "fail"
time to to the generator is "live" time. Maybe 4 secs? Even a 10 yo
gel cell ought to be able to do that.
