Read the Health/Status of USB Modem - Linux

I am using E8231 Huawei Modem.

I a currently debugging a network connectivity issue and a way to see the health of the USB Modem would be great.

The USB Modem has LED indicators on them which tell the status of the connection(Connecting/connected to 3g/3g+/offline).

I would like to know the same programmatically or from linux shell, what can I do?

you can use echo, putty, socat,... to send AT commands to the modem, see https://unix.stackexchange.com/questions/97242/how-to-send-at-commands-to-a-modem-in-linux , https://brunomgalmeida.wordpress.com/2012/04/06/send-at-commands-to-usb-modem , https://content.konekt.io/blog/using-at-commands-with-the-huawei-e303/
