Yes, I tried the "=:13.60" with no luck ;) So there's only *one* driver in the subversion trunk for the RS232 and USB interfaces? No more distinction between the interfaces.

My 1000VA one is at 24V (nominal) but it works well alone with no modification. > You might try the 'blazer_ser' and 'blazer_usb' drivers from the trunk.

Understood, I'll try downloading/compiling tomorrow, I'm very curious to see the new driver ;) More, as an information, I have the 600VA UPS running 24h/7d with a little server and a PC-firewall attached, so I can test the new drivers in production 24/7 *after* I've tried them a little bit at the other 2 UPSes where I have no critical systems (and so not on 24/7 test). My plan is to understand how buildbot and subversion work tomorrow, then try to compile/install the last trunk in the evening (UTC+1) on my non-critical systems. I'll be back :) -- Fr3ddie [email protected] Home Page: http://www.fr3ddie.it OpenPGP Public Key available on my website Two big products come from the University of California: UNIX and LSD.
