It certainly didn't seem to. I think it (the Windows software) was set to
shut down once the battery got down to 2 minutes of runtime. Re-applying the
power to the UPS caused the load power to be re-applied immediately.

Yeah, if nobody had a better answer then I had pretty much resigned myself
to doing this. I assume something similar is available under Linux to
capture the traffic from NUT that way? I also considered checking the source
of some of the others, like APCUPSD to see if they send different commands.
