The meter map is basically a bitmap that indicates what variables are output
(and in what format) by the UPS. You will likely see a variable, 'not mapped'
or nothing. The variables and 'not mapped' items are output by the UPS in the
measurement block, and the map tells nut how to read it. 'Unmapped' means that
there is a variable there that nut is ignoring, and the xcp spec can tell you
what it is, so you can determine if it is useful (that was the case on my
Prestige - plain 'output voltage' was not present in the map, but 'phase 1
output voltage' was, which was unmapped and not used. I tweaked the maps, and
was good.

And yeah, I spent too much time in the serial side of this driver getting my
unit to work, but the good news is that the code is pretty easy to follow, and
with very good debug output.
