[Nut-upsuser] Info for decoding report from UPS

[Jim Klimov]

Ah, I see. My take is that using or adapting something that exists is
easier than starting from scratch - but to each their own. Surely you'll
learn a lot :)

Still, just to clarify: after the NUT v2.8.0 release I began a slow revival
of old NUT for Windows effort (abandoned a decade ago at 2.6.5-8 based
branch), so now there are regular native win64 (CLI) builds regularly
produced by CI, as a tarball of a result of `make install` area (plus the
dependency DLLs). They can run in-place and do work for testing NUT
behaviors on the platform, but are not "properly packaged" yet, have no
installer, and indeed may need fiddling with USB libraries in particular
(so that Windows "HID Battery" driver won't get in the way and would let
libusb handle that node for NUT), but still sounds easier to give this a
shot before constructing something new. This OS integration bit may have
worked in that older 2.6.5 codebase, just I had no time to look hard at
this recently, and nobody else stepped up either. PRs to complete this part
are welcome, so fiddling would not be needed ;)

Quoting from a recent post:

For kicks, you can try starting different drivers from a NUT for Windows
build - I'd be interested to know if it actually picks up a serial port
device (with nutdrv_qx as a  first stop, to test for Megatec Qx protocol
family). Getting USB handled directly may be quite a hassle currently
(without a proper elevated installer), but may be doable too:

Can try a pre-built tarball from CI https://ci.appveyor
.com/project/nut-travis/nut/history
e.g. for currently-latest master-branch build: https://ci.appveyor
.com/project/nut-travis/nut/builds/48009107/artifacts => https://ci.appveyor
.com/api/buildjobs/kn42sp8aek4md9va/artifacts/NUT-for-Windows-x86_64-SNAPSHOT-2.8.0.725-master.7z

Good luck,
Jim
