Ah! I see that now. Yes, I would have been clued in better if I had
seen something like Serial-DB9 next to the 'apcsmart' module.

Thank you for that pointer on where to look. I was swimming in
After reviewing the man pages and the compatibility web page and
following the INSTALL documentation in the ./doc/ directory, everything
we've tested so far is working beautifully. Due to one of our duel
power-supply file servers that dies if one of the power supplies is
unplugged.. We'll have to schedule some down-time to test every aspect
of our new nut configuration.
Unless I can get a compatible NUT version to compile on Slackware 9.0,
I'm going to have to figure out how our master NUT server can monitor a
signal from another UPS and act on data from that secondary UPS. .. But
I suppose I should post that question in a separate thread.
