hi,
i've bought a 750VA orvaldi ups
http://en.orvaldi.com/index.php/en/product_catalog/product_view/11/162
which holds my hardware (wifi router, cable modem, quad-core with raid and lcd
monitor) for ~15 minutes.
pretty nice result for a cheap (~57 euro) home ups.
in fact, the vendor software for linux is very old (e.g. requires ancient redhat
with qt2),
requires db9 port while shipped product has serial-over-usb converter,
so the nut package is my only hope in this area.
afaics in other orvaldi's data sheets they use megatec protocol, so i've
tested followinf scenario:
1). connect usb cable to ups.

2). add [orvaldi] entry to /etc/ups/ups.conf:
[orvaldi]
driver = megatec_usb
port =
/dev/input/by-id/usb-0665_WayTech_USB-RS232_Interface__V1.0__Baud_rate_2400bps-event-if00
^^^^ this is a udev-maintained symlink to
proper /dev/input/eventX.
desc = "Orvaldi"
3). test the driver:
# /lib/nut/upsdrvctl -u root -D start orvaldi

from the other side, there's a working windows software installed on my
laptop.
i can sniff it with your help to provide required info for further nut
development.
