    Now it doesn't seem to list a Linux driver for your particular UPS but
    I'd have a go with the Linux one as it appears to be common for several
    serial Belkin's. Other than that (and maybe as a better choice) you
    could take a look at NUT at http://www.networkupstools.org/ The driver
    there for the Belkin UPS seems to work OK too with FC1. Check out
    http://quasar.mathstat.uottawa.ca/~selinger/ups/ for a system V
    start/stop program for Belkin-supplied driver and details about the NUT
    serial driver for the Belkin UPS's.

    I just use the serial cable that came with the UPS and it works fine.
    Are you using a serial port connector that is directly on the MB of your
    computer or one of those ones that connect with a little cable? I there
    there are a couple of versions of the wiring for the cable type (I had
    to rewire mine).

    In retrospect, Belkin would not be my first choice for a UPS under
    Linux. MDG seems to have good Linux support.

    Hi Mike
    I lost the cable for the UPS, therefore I had to roll my own.
    I am using the serial port connector that is directly on the MB of my
    computer. I am going to check NUT and the other addresses.

    What is the pinout of your cable?

    Thanks!

    Javier
