Matkapuhelin modeemina/DNA

Asetustiedostot, joiden avulla matkapuhelinta voi käyttää modeemina DNA:n liittymiä varten:

/etc/ppp/peers/dna

# Most GPRS phones don't reply to LCP echo's
lcp-echo-failure 0
lcp-echo-interval 0

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

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

# Show password in debug messages
show-password

# Connect script:
# scripts to initialize the GPRS modem and start the connection,
connect /etc/ppp/dna-connect-chat

# Disconnect script:
# AT commands used to 'hangup' the GPRS connection.
disconnect /etc/ppp/dna-disconnect-chat

# Serial device to which the GPRS phone is connected:
/dev/ttyACM0    # Data cable device file
#/dev/rfcomm0      # Bluetooth device file



# Serial port line speed
115200  # fast enough
#57600

# Hardware flow control:
# Use hardware flow control with cable, Bluetooth and USB but not with IrDA.
crtscts  # serial cable, Bluetooth and USB, on some occations with IrDA too
#nocrtscts # IrDA

# Ignore carrier detect signal from the modem:
local

# 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
0.0.0.0:0.0.0.0

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

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

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

# 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.
