I just wrote this just a couple of minutes ago:
My APC Smart UPS runs fine with upsmon-2.1.3/ from the ports.
upsmon.sh in /usr/local/etc/rc.d/ looks like this:
#!/bin/sh
# see /usr/local/share/doc/upsmon/INSTALL for command line option details
if [ -x /usr/local/sbin/upsmond ]; then
/usr/local/sbin/upsmond -p /dev/cuaa1 -r 20 && echo -n ' upsmond'
fi
I have used cuaa1 (COM2 in dos-parlance) so as to have a mouse on cuaa0
(-p). I also have a small load so I let the system power me for 20 minutes
before shutting down completely (-r).
#ll /dev/cuaa*
crw-rw---- 1 uucp dialer 28, 128 27 Jun 14:00 /dev/cuaa0
crw-rw---- 1 uucp dialer 28, 129 27 Jun 13:10 /dev/cuaa1
and /etc/ttys:
ttyd0 "/usr/libexec/getty std.9600" dialup off secure
ttyd1 "/usr/libexec/getty std.9600" dialup off secure
The program upsstat (in the same port) gives this:

Installation was easy the problem was to get syslogd to log it. Finally
this cured it:
Insert into /etc/syslog.conf:
!UPS
*.* /var/log/upsmon.log
The trick was to find the magic word UPS. I hade to read the sources to
find that one:(
And now the log says something when power is going down:
Jul 30 08:18:25 <daemon.crit> vanheden UPS: Input line power failure
Jul 30 08:18:57 <daemon.crit> vanheden UPS: Input line power failure
Jul 30 08:19:38 <daemon.crit> vanheden UPS: Input line power failure
Jul 30 08:19:38 <daemon.emerg> vanheden UPS: Power Failure - 1127 seconds
to shutdown!
Jul 30 08:20:19 <daemon.crit> vanheden UPS: Input line power failure
[snip snip]
Jul 30 08:38:04 <daemon.emerg> vanheden UPS: Power Failure - 21 seconds to
shutdown!
Jul 30 08:38:45 <daemon.crit> vanheden UPS: Input line power failure
Jul 30 08:38:45 <daemon.emerg> vanheden UPS: Power Failure - System
shutdown now!
[ A clean shutdown at this point ]
Jul 30 10:28:09 <daemon.info> vanheden UPS: upsmond daemon started -
version 2.1.3
Jul 30 10:28:09 <daemon.alert> vanheden UPS: Input line power back
Aug 1 13:10:32 <daemon.info> vanheden UPS: upsmond daemon started -
version 2.1.3
Aug 3 03:26:29 <daemon.crit> vanheden UPS: Input line power failure
Aug 3 03:26:30 <daemon.alert> vanheden UPS: Input line power back
Hope this helps a bit.
