I'm not an APC expert, so there might be slight nuances or updates that I'm
not aware of.
as told, AFAICT any units that use microlink *doesn't* work with serial
but as also told on Apcupsd webpage, USB works (basically) and expansion
cards are another option.

what is part of the nuances is the declination of SmartUPS units: SMX/SMT,
RT XL are the only one mentioned.
are there other SmartUPS models that either use microlink but provides a
minimal set of data, or units still using the old protocol?

anyone that can help clarifying this, preferably with a wrap-up, is very
welcome to do so!
here is the current situation:

and if anyone can provide microlink snoops for analysis, I would be pleased
to take a look at it.

> Does NUT not work in a similar way with these UPS's?

I'll delegate the right answer to Michal. Mine would be "very likely"...
