This is all what we expect. > Battery dies, then status = OB, and then changes to OL. Could be the circuit that is controlling looses power. Since this UPS uses 'contact' closure signalling, there always will be a status (even if the UPS is not actively controlling the modem control lines). > When power is restored, status toggles from OB to OL to OB to OL a few > times and > then stays at OL.

See above. Nothing to be worried about. After the UPS signals OB LB and the server picks this up, this state will be latched and there is no way back. > I did try using the powerpanel driver but that timed out and did not find > the UPS. Apparently, your UPS only supports 'contact closure' signalling or the cable used doesn't have the necessary wires for smart signalling. > Genericups type 7 seems to work the same as type 22. If you look in the manual page for the genericups driver, you'll find the signalling is identical. Adding type 22 was a mistake (since it isn't different from type 7), but since it has been like that for a couple of releases, we can't correct this without breaking things. > Is the genericups driver one that simply monitors the CTS, DTR etc. > signals?

Spot on. Everything is fine and dandy.
