I've got a 420 Back-UPS Pro (a few years old now) & it uses a serial
cable for `smart' mode. I had it working fine on Linux using apcupsd
but have been too lazy to configure it with the cable on FreeBSD as of

I'm pretty sure that you could get it working with a serial cable on
BSD though ie. through the compatabilty layer or porting it - the
software wasn't that complicated back then (hurrahs for serial ports,
boos & hisses for USB :)
