三、4G模块拨号上网
usb0网卡接口默认不会启动，可以使用ifconfig -a查看是否存在，存在则说明4G模块驱动正常，使用ifconfig usb0 up启动，然后使用udhcpc -i usb0自动分配ip和dns，拨号成功就可以访问外网
使用busybox microcom -t 5000 /dev/ttyUSB*，具体要看系统生成的节点，-t 5000是无操作5秒后退出命令行模式，如下/dev/ttyUSB0无法输入命令，/dev/ttyUSB1可以
root@TinaLinux:/# busybox microcom -t 5000 /dev/ttyUSB0
root@TinaLinux:/# busybox microcom -t 5000 /dev/ttyUSB1

OK
# 根据SIM卡运营商输入，移动：CMNET，电信：CTNET，联通：3GNET
# 如下是移动卡的拨号指令，返回OK说明配置成功

AT+QNETDEVCTL=3,1,1
OK
# 可以使用AT+QNETDEVCTL?指令，查看是否联网成功(如下最后一个参数为1，表示联网成功)
