I just confirmed with APC regarding this software setting, and they
confirmed it- but stated categorically that only the Window$ software of
their making could do it. Can you confirm the BSD software will do it?

I think I shocked the guy when he suggested just hook up to another
windows box to change the setting, then put it on whatever machine I
wanted, and I told him that was near impossible- "I wouldn't corrupt my
network with M$"!!!
