Yep, been there done that, just wondered what you guys used.  I'm using a
940-0024C APC Cable (the black one) connected to /dev/cuaa0 with me
attempting to set the port using stty to 2400, 8/n/1 with XON/XOFF flow
control as per the manual.  I've got this all working in NT as the box dual
boots.  Now I'd quite like to get some BSD monitoring going.  are you using
the PowerChute software on FreeBSD ?  If so could I sneak a peek at your
powerchute.ini :-)

Not sure also what line to give stty to get the port set right as it seems
to ignore me ;-)  And I'm also not sure if upsmond is core dumping on me
because of some weirdness in -current.  Shame testing on our production
machines is not an option :(

I'd really quite like to get either powerchute up and running or NUT as this
looks pretty impressive.
