AT commands on CDC interface while using USB RNDIS / CDC-ECM 4G modem (AEGHB-1334)

[jitenshap]

When using a USB 4G modem with CDC-ECM or RNDIS to access the Internet,
is it possible to send arbitrary AT commands to the modem’s CDC-AT port?

Many 4G modems require AT commands such as:

• AT+CGDCONT
• AT+CGAUTH
  for PDP context and authentication, and
• AT+CSQ
  to check signal quality.

Does esp-iot-solution provide an official way to use CDC-AT together with
RNDIS/ECM, or an example of how to open the AT interface of the same device?
