在 Linux 下使用 CDMA 1x USB 无线上网

测试环境: Linux 2.6.16-gentoo-r2 x86_64 AMD Athlon(tm) 64 Processor 3400+ GNU/Linux
硬件设备: 波乐 5188 USB CDMA 1x Moderm， 联通新时空卡
需要软件: ppp wvdial
安装过程:

1. 安装软件
   

   代码:

   
   emerge ppp wvdial
   

   
   
2. 修改用户组
   

   代码:

   
   usermod -aG dialout 用户名
   

   
   
3. 运行配置生成文件
   

   代码:

   
   wvdialconf /etc/wvdial.conf
   editing `/etc/wvdial.conf'.
   Scanning your serial ports for a modem.

   Found an USB modem on /dev/ttyACM0.
    /etc/wvdial.conf: Can't open '/etc/wvdial.conf' for reading: No such file or directory
    /etc/wvdial.conf: ...starting with blank configuration.
    Modem configuration written to /etc/wvdial.conf.
    ttyACM0: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
    

   
   
4. 修改配置文件 nano -w /etc/wvdial.conf
   

   代码:

   
    [Dialer Defaults]
    Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
    Modem Type = USB Modem
    Phone = #777
    ISDN = 0
    Username = CARD
    Init1 = ATZ
    Password = CARD
    Modem = /dev/ttyACM0
    Baud = 460800
    

   
   

使用说明:

• 运行
  

  代码:

  
   modprob ppp
   wvdial
   

  
  
• 看到的结果如下：
