Whoops, I thought I saw something about USB in your original email. A null-modem serial cable would be easier to build (for the smart interface), but I think a good portion of what I mentioned applies to serial as well as USB (on the software side). It would probably be a lot simpler to emulate a serial UPS than a USB UPS. You still might get more APC-specific information from the apcupsd.org lists, though the code for either the NUT apcsmart serial driver or the equivalent apcupsd serial driver would be a good starting point to build such an emulator. _______________________________________________ Nut-upsuser mailing list Nut-upsuser@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/nut-upsuser
