May I use this opportunity to "readvertise" a script I tried to bring to your
collective attention some months ago. It's attached to this post as "bluepin". 
It works in text mode, supports a file containing address/pin mappings, and
uses the dialog utility to bring up a text-mode prompt on a spare virtual
terminal for devices not listed in the file. Please give it some consideration.
I'll be glad to enhance it as necessary regarding whatever features it's
missing or could use in addition to what it already does. See the comments at
the top of the script for more detail.

#!/bin/sh
# This script has been written by Dave Mielke <dave@mielke.cc>. It's a light 
# weight, text mode, Bluetooth PIN helper script. Its dependencies are:
# *  /bin/sh  The standard system command shell.
# *  open     A command which opens a free virtual terminal.
# *  dialog   A command which presents a text-mode dialog.
#
# The file /etc/bluetooth/pins is searched for a line corresponding to the 
# Bluetooth address of the device. Each line of this file should contain the
# address of a device and its PIN, in that order, separated by space. If the
# address is found then the corresponding PIN is automatically supplied. If
# it's not found then the user is prompted via a text-mode dialog in a free 
# virtual terminal. The console automatically returns to the original virtual
# terminal as soon as the PIN is entered.
