I tried a slight variant of what you suggested above (after starting
upsmon), e.g.

while true
do
cat /dev/ttyS0 | od -xc
sleep 1
done > ttyS0.out &

Letting it run for awhile, I get:

% cat ttyS0.out

The powercom driver in nut doesn't seem to work at all even though
upsmon starts up with the message:

UPSMON: The UPS serial port use /dev/ttyS0.
UPSMON: Ac Fail count down is seted 300 secs.
