[Nut-upsdev] [Nut-upsuser] APC Modbus support is finally here!

[Jim Klimov]

Thanks again,

  Great to see confirmations of more and more things working!

the correct testing procedure?

At least by intent of this new feature -- yes. Normally the drivers are not
allowed to pass these dangerous commands unless started specifically for
killpower handling late in the system shutdown. Since NUT v2.8.1 however
there's this safety switch to toggle and then an instant command should be
usable. But as this is a relatively recent addition to the codebase and it
is not integrated with practical shutdowns in any packages yet (AFAIK) to
avoid killing a driver daemon to restart it as the driver tool just for the
killpower command, it has not seen much real-life testing -- so it is
possible that some bugs lurk here too.

Regarding shutdowns triggered due to calibration - the `CAL` state should
be specially handled with regard to `OB`/`LB` in `upsmon` since recently.
However this driver seems to use `TEST` here? Raised a question in
https://github.com/networkupstools/nut/pull/2184 discussion (also
referenced your replies there). Actually, now I wonder (did not test) how
`upsmon` interacts with `upssched` in case of calibrations, if this is
suppressed or not...
