that's indeed still working like that: we still have only string or enum, so numeric (probably including both float and integer) is still lacking, and is somehow the default when you get an "UNKNOWN type" message. it's still more a cosmetic issue, since everything is passed through string, and it's up to the driver, in the end, to reformat the value as expected by the device / protocol. cheers, Arnaud -- Linux / Unix Expert R&D - Eaton - http://powerquality.eaton.com Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org/ Debian Developer - http://www.debian.org Free Software Developer - http://arnaud.quette.free.fr/ _______________________________________________ Nut-upsdev mailing list [email protected] http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsdev
