   PPP (point-to-point protocol) support

[*]     PPP multilink support (EXPERIMENTAL)

[*]     PPP filtering

     PPP support for async serial ports

     PPP support for sync tty ports

     USB driver for GSM and CDMA modems

 

4.2、linux内核修改

drivers/usb/serial/option.c

static struct usb_device_id option_ids[] = {

…

};

在这个数组中添加两项

        { USB_DEVICE(0x19d2, 0x0031) },

        { USB_DEVICE(0x19d2, 0x0034) },

4.3、linux内核编译

make zImage

make modules

 

5、             3G模块的使用

insmod ppp_mppe.ko

 

5.2、加载USB文件系统

mount -t usbfs usbfs /proc/bus/usb

 

5.3、ZTE-mf637u（中国联通）的使用

5.3.1、配置文件/etc/usb_modeswitch.setup

# Configuration for the usb-modeswitch package, a mode switching tool for

# USB devices providing multiple states or modes

#

# This file is evaluated by the wrapper script "usb_modeswitch" in /lib/udev

# To enable an option, set it to "1", "yes" or "true" (case doesn't matter)

# Everything else counts as "disable"

 

 

# Disable automatic mode switching globally (e.g. to access the original

# install storage)

 

DisableSwitching=0

 

 

# Enable logging (results in a extensive report file in /var/log, named

# "usb_modeswitch_"

 

EnableLogging=0

5.3.3 ZTE-mf637u（中国联通）的操作步骤

5.3.3.1、设置环境变量

export PATH= /works/wvdial-1.54.0/install/bin: /works/cdma/install/bin :$PATH

export LD_LIBRARY_PATH= /works/wvdial-1.54.0/install/lib: /works/cdma/install/lib:$LD_LIBRARY_PATH

5.3.3.2、插入ZTE-mf637u（中国联通）无线网卡

5.3.3.3、等待5秒钟左右、运行usb-modeswitch -W

5.3.3.4、运行wvdial

--> WvDial: Internet dialer version 1.54.0

--> Cannot open /dev/ttyUSB2: Cannot get information for serial port.

--> Cannot open /dev/ttyUSB2: Cannot get information for serial port.

--> Cannot open /dev/ttyUSB2: Cannot get information for serial port.

 

解决：(两种方法)

5.3.3.4.1将wvstreams-4.0.1/streams/wvmodem.cc

#if HAVE_LINUX_SERIAL_H

改为

#if 0

 

5.3.3.4.2. wvstreams-4.0.1的配置命令增加ac_cv_header_linux_serial_h=no

即./configure --prefix=/works/wvdial-1.54.0/install --host=arm-linux CFLAGS=-I/works/cdma/install/include LDFLAGS=-L/works/cdma/install/lib/ --with-zlib=/works/cdma/zlib-1.2.5 --with-openssl=/works/cdma/openssl-0.9.8n --without-dbus --with-pam=no --with-tcl=no --with-qt=no ac_cv_header_linux_serial_h=no

重新编译。

export LD_LIBRARY_PATH=/root/cdma:$LD_LIBRARY_PATH

5.4.2.2、插入ZTE-mu351（中国移动）无线网卡

5.4.2.3、等待5秒钟左右、运行eject /dev/sr0。（5.3.3.3也可以使用此方法）

5.4.2.4、运行wvdial

--> WvDial: Internet dialer version 1.54.0

--> Initializing modem.

--> Sending: ATZ
