Linux系统通过手机GPRS功能无线上网.doc

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: S0 S1 S2 S3 WvModem: Cannot get information for serial port.ttyACM0: ATQ0 V1 E1 - OKttyACM0: ATQ0 V1 E1 Z - OKttyACM0: ATQ0 V1 E1 S0=0 - OKttyACM0: ATQ0 V1 E1 S0=0 &C1 - OKttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 - OKttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 - OKttyACM0: Modem Identifier: ATI - ENZOttyACM0: Speed 4800: AT - OKttyACM0: Speed 9600: AT - OKttyACM0: Speed 19200: AT - OKttyACM0: Speed 38400: AT - OKttyACM0: Speed 57600: AT - OKttyACM0: Speed 115200: AT - OKttyACM0: Speed 230400: AT - OKttyACM0: Speed 460800: AT - OKttyACM0: Max speed is 460800; that should be safe.ttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 - OKFound 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 defaultsInit1 = at+cgdcont=1,ip,cmwapModem Type = USB ModemISDN = 0Phone = *99*1#Modem = /dev/ttyACM0Username = anyCarrier Check = noPassword = anyBaud = 460800保存后，使用wvdial拨号 sudo wvdial使用超级用户操作，不然无法会提示设备忙，或更改用户权限。 - WvDial: Internet dialer version 1.60- Cannot get information for serial port.- Initializing modem.- Sending: at+cgdcont=1,ip,cmwapat+cgdcont=1,ip,cmwapOK- Modem initialized.- Sending: ATDT*99*1#- Waiting for carrier.ATDT*99*1#CONNECT7f#!06 Carrier detected.
