Hi,
I'm new to NUT. I've installed Fedora 8 and NUt along with it. I'm
now
having a go at getting my Unitek Alpha 1200sx UPS to work and shutdown the
box automatically. I know this isn't officially supported but I'm trying
my
luck...
I've seen that other Unitek UPSs use the 'megatec' driver however
I'm unsure
whether this will do the trick. My UPS comes with a USB connection.
Following is some relevant output:

--------------------------------------
This therefore seems to me like some serial-over-usb type protocol. I'm
therefore unsure as to what driver to try and use (megatec, megatec_usb) and
what device to point it to /dev/ttyS?
I was hoping someone could point me in the right direction.
Many thanks in advance.
Joe

I'm therefore unsure as to what driver to try and use (megatec, megatec_usb) and what device to point it to /dev/ttyS?If that UPS has only an USB connection, then megatec doesn't work. "megatec_usb" might work, and the port should be "auto". If it doesn't detect your UPS on the first try, check out the additional options for the driver. -- Carlos Rodrigues
