instalacja modemu GPRS RS232

[kewy]

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.
Kris

W internecie jest wiele poradników na ten temat ;-)

W skrócie to musisz utworzyć pliki

/etc/ppp/peers/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

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/ircomm0   # IrDA serial port one 
/dev/rfcomm0   # Bluetooth serial port one 
#/dev/ttyUSB0   # USB serial device, for example Orange SPV 

# Serial port line speed

# 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!

Musisz tylko zmienić linie według swojego operatora:

OK 'AT+CGDCONT=1,"IP","internet"'
OK ATD*99#

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.)

/dev/rfcomm0 # Bluetooth serial port one

Dla Ciebie dobry będzie interfejs

# /dev/ttyS0 for serial port (COM1 in Windows)

Zakomentuj rfcoom0 i odkomentuj ttyS0

Później połączenie ustanawia się przez
