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. ttys0<*1>: atq0 v1 e1 -- failed with 2400 baud, next try: 9600 baud  ttys0<*1>: atq0 v1 e1 -- failed with 9600 baud, next try: 115200 baud  ttys0<*1>: atq0 v1 e1 -- and failed too at 115200, giving up.  ttys1<*1>: atq0 v1 e1 -- failed with 2400 baud, next try: 9600 baud  ttys1<*1>: atq0 v1 e1 -- failed with 9600 baud, next try: 115200 baud  ttys1<*1>: atq0 v1 e1 -- and failed too at 115200, giving up.  modem port scan<*1>: s2 s3  ttyacm0<*1>: atq0 v1 e1 -- ok  ttyacm0<*1>: atq0 v1 e1 z -- ok  ttyacm0<*1>: atq0 v1 e1 s0=0 -- ok  ttyacm0<*1>: atq0 v1 e1 s0=0 &c1 -- ok  ttyacm0<*1>: atq0 v1 e1 s0=0 &c1 &d2 -- ok  ttyacm0<*1>: atq0 v1 e1 s0=0 &c1 &d2 +fclass=0 -- ok  ttyacm0<*1>: modem identifier: ati -- error  ttyacm0<*1>: speed 4800: at -- ok  ttyacm0<*1>: speed 9600: at -- ok  ttyacm0<*1>: speed 19200: at -- 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.  /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：
  

  代码:
