# start-bt-modem: Start "dial-up networking" via Bluetooth with a Treo 700p.

# For this script to work, you must already have paired your computer and 
# the phone, and the computer should appear in the "trusted devices list" 
# on your Treo.  
# 
# You'll need to change the PHONE_BT_ADDR variable to match your phone's 
# Bluetooth address.  To find this, set your Treo's Bluetooth visibility 
# to "Temporary" and run 'hcitool scan' on your Linux box.
