Hi Vitor,

please, keep the list cc'ed since other might interested in (either the
solution, or their 2 cents to the discussion). Moreover, knowing that
I'm not an author of the megatec / blazer drivers, things might be
obvious to these guys and not to me...

I realise that I completely forgot to tell you to test blazer_usb, which
will soon replace the megatec ones.
the best would be to give it a quick shot through the development tree,
without installing anything (inplace testing).

I've never played with this protocol, but it seems that you will have to
use the various parameters to finalise its setup:
mfr, model and battvolts in ups.conf

first try blazer since iirc, it's more smart.

you should really take a look at blazer's manpage:
