# A wrapper for efax to be used together with a bluetooth mobile phone
# and tdeprintfax to send faxes via bluetooth from any kde application.
#
# This script does basically the same as the "efax" command, which is
# already configured in tdeprintfax.
# The difference is that kbtfax will ask you which bluetooth device
# you want to connect to and then sets up a virtual serial device
# with the rfcomm utility. Then the fax command is started and 
# finally the rfcomm binding is released.

# Use the following fax command when printing (without the 'FAXCMDLINE=')
FAXCMDLINE="kbtfax NAME=%user PAGE=%page FROM=%from send %res %number %files"
# This is the same as for eFax, but without the DEV parameter

# If your device does not support the fax profile
# and works of the serial port profile instead,
# you will have to change this script to use
# SPP instead of FAX for the search UUID.
# Default: SEARCH_UUID="FAX"
SEARCH_UUID="FAX"

# This will list all possibly relevant services, including fax,
# dialup and serial port profile. It will also list many
# unrelated services like obex push etc., but it should be
# easy to see what's the right choice.
#SEARCH_UUID="0x0003"

# If you don't want to use the default rfcomm 
# device (/dev/rfcomm1) you can specify another one here.
# Default: RFCOMM_DEVICE=1
RFCOMM_DEVICE=1
