Interestingly, NUT has *two* serial APC drivers, and I vaguely remember that there are older units that fall through the cracks even with those two:

- https://networkupstools.org/docs/man/apcsmart.html (has some tips for identifying generations)
- https://networkupstools.org/docs/man/apcsmart-old.html

That said, between the logs from the working apcupsd code, and debug logs from maybe apcsmart-old, we should be able to figure something out.
