Linux系统通过手机GPRS无线上网

首先，要有一台具备GPRS且带有modem功能的手机，以下以palm treo 650为例。

650是不带modem功能，要通过软件实现，下载 USB modem软件并安装在650上。该软件支持蓝牙和usb数据线两种模式!

下面首先看系统是否能检测到modem

sudo wvdialconf

Editing `/etc/wvdial.conf'.

Scanning your serial ports for a modem.

Modem Port Scan<*1>: S0 S1 S2 S3 
WvModem<*1>: Cannot get information for serial port.
ttyACM0<*1>: ATQ0 V1 E1 -- OK

ttyACM0<*1>: Speed 38400: AT -- OK
ttyACM0<*1>: Speed 57600: AT -- OK
ttyACM0<*1>: Speed 115200: AT -- OK
ttyACM0<*1>: Speed 230400: AT -- OK
ttyACM0<*1>: Speed 460800: AT -- OK
ttyACM0<*1>: Max speed is 460800; that should be safe.
ttyACM0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK

Found an USB modem on /dev/ttyACM0.
Modem configuration written to /etc/wvdial.conf.
ttyACM0: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

如果出现以下信息则能检测modem且将配置自动写入 /etc/wvdial.conf文件。你modem的设备文件为/dev/ttyACM0

由于配置文件为普通拨号而建立，所以不适合grps拨号，要作以下修改

[Dialer defaults]
Init1 = at+cgdcont=1,"ip","cmwap"
Modem Type = USB Modem
ISDN = 0
Phone = *99***1#
Modem = /dev/ttyACM0
Username = any
Carrier Check = no
Password = any
Baud = 460800
