"Is it a list of those variables" -> I would say that for a given variable called <varname> (on <upsname>), it returns the set of possible values that can be read or written. I don't think there is a way to query upsd for just the list of ENUM variables, the way it is possible to query for RW variables. Several UPSes have settings which can be cycled via a front panel button (e.g. sensitivity or voltage thresholds), and if those are exposed in the protocols, then the drivers should use ENUMs to pass that along. This is not currently the case for usbhid-ups: https://github.com/networkupstools/nut/issues/134 -- Charles Lepple clepple@gmail _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
