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:



安装软件
代码:

emerge ppp wvdial



修改用户组
代码:

usermod -aG dialout 用户名



运行配置生成文件
代码:

wvdialconf /etc/wvdial.conf
editing `/etc/wvdial.conf'.

ttyACM0: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"



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:
