Ah, OK. I wasn't sure if it was being listed as supported but not executing.

There is definitely code in the apc-mib.c file that appears to support
it, via the OID I mentioned:

'4) Does the calibration work if you manually run something like:
 "snmpset <host-and-community>
PowerNet-MIB::upsAdvTestRuntimeCalibration.0 i 2" ?
(if it does, you should be able to stop it by changing the "2" to a "3").'

Again, Arnaud or someone else with more experience with that driver
might be able to help troubleshoot this better.
