rfcomm0 { bind yes; device 00:1F:00:31:96:CE; channel 3; comment "Serial port Nokia 6300 KH"; }which uses pairing that was set up before. For dialup I set up /etc/ppp/peers/xs4all-gsm-data with:
# There should be a matching entry with the password in /etc/ppp/pap-secrets # and/or /etc/ppp/chap-secrets. user "koos" # MUST CHANGE: replace ******** with the phone number of your provider. # The /etc/chatscripts/pap chat script may be modified to change the # modem initialization string. connect "/usr/sbin/chat -v -f /etc/chatscripts/pap -T 0346550455" # Serial device to which the modem is connected. /dev/rfcomm0The rest of the file were default values from /etc/ppp/peers/provider. The file /etc/ppp/pap-secrets was updated with a line with the password for xs4all.
The result: working, not too fast (9600 bps) Internet.
