hmmm... strange... what freebsd version are you using (uname -a)? did
you try to use rfcomm_sppd(1)? something like

# rfcomm_sppd -a mytreo -c 1 -t /dev/ttyp1

then in another window 

# cu -l /dev/ttyp1

and try to type "AT" to see if the phone returns "OK" back?

note: you might need to try different tty number to find free one,
i.e. /dev/ttyp2, /dev/ttyp3 etc. tty name must match in both commands.

thanks,
