This may not be simple at all. APC is providing no support to the NUT
developers in this area, so all we have is what we got from reverse
engineering.

Which version is this?
> Instant commands supported on UPS [apc]:
> beeper.disable - Disable the UPS beeper
> beeper.enable - Enable the UPS beeper
> beeper.mute - Temporarily mute the UPS beeper
> beeper.off - Obsolete (use beeper.disable or beeper.mute)
> beeper.on - Obsolete (use beeper.enable)
> load.off - Turn off the load immediately
> load.off.delay - Turn off the load with a delay (seconds)
> load.on - Turn on the load immediately
> shutdown.reboot - Shut down the load briefly while rebooting the UPS
> shutdown.return - Turn off the load and return when power is back
> shutdown.stayoff - Turn off the load and remain off
> shutdown.stop - Stop a shutdown in progress
> test.panel.start - Start testing the UPS panel
> test.panel.stop - Stop a UPS panel test
More interesting, what does the output of 'upsc apc' look like?

That doesn't make sense. The report descriptor says this command is
available, but when we want to use it, it just ignores us.
> instcmd: FAILED
> Shutdown failed!
This doesn't look like the SVN trunk, is it?

None of the active NUT developers has access to an APC CS-500 if I'm
not mistaken. So unless you're willing to do some research/work here,
this likely will stay that way.
