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. -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
