# Serial cable, IrDA, Bluetooth and USB pppd options for GPRS phones.

# Keep pppd attached to the terminal:
# Comment this to get daemon mode pppd

# Debug info from pppd:
# Comment this off, if you don't need more info

# Connect script:
# scripts to initialize the GPRS modem and start the connection,
# wvdial command is for Orange SPV while other phones should work with chat
connect /etc/ppp/peers/gprs-connect-chat_V3x_vodafone
#connect "/usr/bin/wvdial --chat --config /etc/ppp/peers/gprs-wvdial.conf
#radiolinja_usb_orange_spv"

# Disconnect script:
# AT commands used to 'hangup' the GPRS connection.
disconnect /etc/ppp/peers/gprs-disconnect-chat_V3x

# Serial device to which the GPRS phone is connected:
# /dev/ttyS0 for serial port (COM1 in Windows),
# /dev/ircomm0 for IrDA,
#/dev/ttyUB0 #for Bluetooth (Bluez with rfcomm running) and
#/dev/ttyUSB0 for USB
#/dev/ttyS0     # serial port one
#/dev/ttyS1     # serial port two
#/dev/ircomm0   # IrDA serial port one
/dev/rfcomm0    # Bluetooth serial port one
#/dev/ttyUSB0   # USB serial device, for example Orange SPV

# Serial port line speed
460800  # fast enough
#57600  # perhaps usefull with IrDA

# Hardware flow control:
# Use hardware flow control with cable, Bluetooth and USB but not with IrDA.

# Ignore carrier detect signal from the modem:

# IP addresses:
# - accept peers idea of our local address and set address peer as 10.0.0.1
# (any address would do, since IPCP gives 0.0.0.0 to it)
# - if you use the 10. network at home or something and pppd rejects it,
# change the address to something else
#:10.0.0.1

# pppd must not propose any IP address to the peer!

# Accept peers idea of our local address
ipcp-accept-local

# Add the ppp interface as default route to the IP routing table

# DNS servers from the phone:
# some phones support this, some don't.
usepeerdns

# ppp compression:
# ppp compression may be used between the phone and the pppd, but the
# serial connection is usually not the bottleneck in GPRS, so the
# compression is useless (and with some phones need to disabled before
# the LCP negotiations succeed).

# The phone is not required to authenticate:
noauth

# Username and password:
# If username and password are required by the APN, put here the username
# and put the username-password combination to the secrets file:
# /etc/ppp/pap-secrets for PAP and /etc/ppp/chap-secrets for CHAP
# authentication. See pppd man pages for details.
# Example, Radiolinja operator pap-secrets:
#user "rlnet"

# Asyncmap:
# some phones may require this option.
#asyncmap 0

# No magic:
# some phones may require this option.
#nomagic

# Require PAP authentication:

# Description:
# chat script to open Radiolinjas GPRS service with GPRS phones. If ppp
# negotiation stalls, try restarting the phone. To try with other GPRS
# operator setting, change the PDP contex setting. The settings work with
# most Ericsson models, but Nokia 8310 and 30 do not support QoS parameters
# with AT commands, so just delete those lines and it'll work.
#
# Set PDP context CID=1, protocol=IP, APN=internet:
# AT+CGDCONT=1,"IP","web.omnitel.it","",0,0
#
# Set CID=1 QoS requirements from the network, not supported by Nokia:
# AT+CGQREQ=1,0,0,0,0,0
#
# Set CID=1 minimum acceptable QoS parameters, not supported by Nokia:
# AT+CGQMIN=1,0,0,0,0,0
#
# 'Call' CID=1 (activate PDP context one, perform GPRS attach):
# ATD*99#
#
# Some phones like the Orange SPV (yes, the Microsoft Smartphone) use this
# dial string to start GPRS connection:
# ATD*99#
