[plug] UPS & powerd

[Brian Tombleson]

It comes with a (serial?) cable that says it plugs into a standard serial
port .. (re-checking doco..) .. "communicate to your computer via your DB-9
communication port" .. yep.

They also have some software available off the net, but it requires Java
Virtual Machine for RH-Linux.  :( .. which I don't want to worry about on a
supposedly dedicated comms server.

Thus trying with powerd.

Thanks for you help anyway, I'll have to try something else for now.

- Brian.
