Software test
Our Linux prebuilt system has added driver of 4G module.It will be auto loaded when system startup. And also use ls to confirm
it.
# ls /dev/ttyUSB*
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3 /dev/ttyUSB4
The Linux system of MYD-C8MMX series board has provider ppp package.You can just enable ppp0 device, it will auto dial-up.
# ifup ppp0
# ifconfig ppp0
