AT modem networking on PocketBeagle

I would like to connect a Quectel BG96 Click board to a PocketBeagle
The hardware side is rather straight forward: install the expansion headers and click in the board.
LEDs light up and off you go.

The modem is not recognised by the operating system: how would he know there is this specific device connected to the UART?
No EEPROM installed, no Cape overlay available.

This can be solved using traditional techniques, if required as the UART I would use is /dev/ttyS4, which is available anyhow.

How I can I explain the operating system that this specific device is installed and listening on /dev/ttyS4/?

If I understand correctly the device is known by the kernel but is expected to connect over USB.

Hi Gwen,
