Does anyone have an APC UPS working properly with Linux? I've been using
Tom Webster's Genpowerd, trying to figure out which serial lines do what.
APC is less than helpful, and I'd rather not sign a NDA and fork over $50,
just so I can make my UPS do what it was supposed to do in the first
place.

Has anyone had any luck, either with Genpowerd or Miguel's Powerd? I'd
like to use either the Win95 cable or the NT cable, which shipped with the
UPS, rather than build my own (though I could build one if I had clear,
definite plans and assurance that it works).

Also, can anyone explain to me the difference between "smart" and "simple"
signaling modes, and how the UPS knows which mode to use?

My UPS is a Back-UPS Pro 280 (plug-and-pray). Thanks for any hints anyone
can share with me.

Hi Jeff,

I have my SUVS420 working with the SCO UNIX version of APC's
PowerChute v/s software. This is in conjuction with the supplied
cable. I think the SUVS's are identical to the BP's, except for
the included software.

I realize this doesn't help you much at this point, but I thought
I'd let you know.

I'm using genpowerd with an APC Back-UPS 600. The cable is a home-built
one, described in the genpower docs as "Jim's APC Back-UPS/Smart-UPS
Windows NT Cable" and as type apc2-nt. (You might need a different one
for your model; there are at least two diagrams for APC cables in the
docs.) It wasn't difficult to build, at least not for me, and I haven't
built more than 3 or 4 cables in my life. Everything works fine, and
it's gotten me through several power failures with perfect performance.
