Hi! For somebody having an interest, there is a driver for APC BH500INET. It uses neon library and based loosely on netxml-ups driver. It have a base functionality and can not be used to set any ups parameters (althougth in theory it is possible). I use it for about two years and it causes no problems, so I guess it can be used, on the other hand I already just vaguely can remember how it does work. I have attaching here sources and a patch against drivers/Makefile.am to build it against version 2.7.4 of Network UPS Tools. -------------- next part -------------- A non-text attachment was scrubbed...
