I have to use the thing on a regular basis. Connection speed is
turtle-slow by today's standards, but it works, and aside from the
bluez package it only requires wvdial one.

A sample implementation is:

# cat /etc/network/if-pre-up.ppp0
/usr/bin/rfcomm connect /dev/rfcomm0 xx:xx:xx:xx:xx:xx &
while [ ! -r /dev/rfcomm0 ]; do
        /bin/echo "Waiting for /dev/rfcomm0 ..."
        /bin/sleep 1
done

# cat /etc/network/if-post-down.ppp0
pkill -9 rfcomm

# grep -A1 ppp0 /etc/network/interfaces
iface ppp0 inet wvdial
    pre-up /etc/network/if-pre-up.ppp0
    metric 1
    post-down /etc/network/if-post-down.ppp0

# cat /etc/wvdial.conf
