instalacja modemu GPRS RS232
kewy - 27-02-2009 15:34
Witam serdecznie.
Chciałbym pod Linuksem zainstalować modem GPRS Wavecom.
Nie wiem jak to zrobić skąd ściągnąć sterowniki. Na stronie producenta nie znalazłem nic.
W Windowsie instalowałem go jako modem standardowy o prędkości 19200.
Modem jest podłączony do RS232.
Czy możecie mnie nakierować?
Dziękuję i pozdrawiam.

W internecie jest wiele poradników na ten temat ;-)
W skrócie to musisz utworzyć pliki
/etc/ppp/peers/gprs
# File: gprs
#
# Description:
# Serial cable, IrDA, Bluetooth and USB pppd options for GPRS phones.
# Keep pppd attached to the terminal:
# Comment this to get daemon mode pppd
#nodetach
updetach
# Opcja updatach oznacza, ze pppd odlaczy sie od terminala dopiero
# gdy zostanie nawiazane polaczenie.
# Debug info from pppd:
# Comment this off, if you don't need more info
debug
# Show password in debug messages
show-password
# Connect/Disconnect scripts:
connect "/usr/sbin/chat -v -f /etc/chatscripts/gprs-connect-chat"
disconnect "/usr/sbin/chat -v -f /etc/chatscripts/gprs-disconnect-chat"
# Serial device to which the GPRS phone is connected:
# /dev/ttyS0 for serial port (COM1 in Windows),
#/dev/ircomm0
# /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
115200 # fast enough
#57600 # perhaps usefull with IrDA
# Hardware flow control:
# Use hardware flow control with cable, Bluetooth and USB but not with IrDA.
crtscts # serial cable, Bluetooth and USB
#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
:10.0.0.1
# 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.

novj
nobsdcomp
novjccomp
nopcomp
noaccomp
# 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:
# "rlnet" * "internet" *
user "internet"
# Asyncmap:
# some phones may require this option.
#asyncmap 0xa0000
# No magic:
# some phones may require this option.
#nomagic
# Require PAP authentication:
# some phones may require this option.

/etc/charscripts/gprs-connect-chat
# File: gprs-connect-chat
#
# Description:
#
# Set PDP context CID=1, protocol=IP, APN=internet:
# AT+CGDCONT=1,"IP","internet","",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***1#
#
# Some phones like the Orange SPV (yes, the Microsoft Smartphone) use this
# dial string to start GPRS connection:
# ATD*99#
#
# The actual chat script:
TIMEOUT 5
ECHO ON
ABORT '\nBUSY\r'

ABORT '\nNO ANSWER\r'
ABORT '\nNO CARRIER\r'
ABORT '\nNO DIALTONE\r'

'' \rAT
TIMEOUT 12
SAY "Press CTRL-C to close the connection at any stage!"
SAY "\ndefining PDP context...\n"
OK ATH
OK ATE1
OK 'AT+CGDCONT=1,"IP","internet"'
OK ATD*99#
TIMEOUT 22
SAY "\nwaiting for connect...\n"
CONNECT ""
SAY "\nConnected."
SAY "\nIf the following ppp negotiations fail,\n"
SAY "try restarting the phone.\n"
/etc/charscripts/gprs-disconnect-chat
# File: gprs-disconnect-chat
#
# send break
exec /usr/sbin/chat -V -s -S
ABORT "BUSY"
ABORT "ERROR"
ABORT "NO DIALTONE"
SAY "\nSending break to the modem\n"
"" "\K"
"" "+++ATH"
SAY "\nPDP context detached\n"
Musisz tylko zmienić linie według swojego operatora:
Akurat to działa dla orange. W pliku /etc/ppp/peers/gprs musisz wybrać jeszcze odpowiedni port (ja akurat mam wybrany /dev/rfcoom0/ bo łącze się po bluetooth.)
Dla Ciebie dobry będzie interfejs
Zakomentuj rfcoom0 i odkomentuj ttyS0
Później połączenie ustanawia się przez
sudo pppd call gprs
