Cinterion MV-32W at command port missing in mmcli (v1.20.0) output

When using a MV-31W (Cinterion PID 0x00B3 USB Mobile Broadband) mmcli -m 0 reports in the System section:

primary port: cdc-wdm0

ports: cdc-wdm0 (mbim), ttyUSB0 (at), wwan0 (net)

A MV-32 (Cinterion PID 0x00F1 USB Mobile Broadband) only shows:

primary port: cdc-wdm0

ports: cdc-wdm0 (mbim), wwan0 (net)

...but ttyUSB0 is available and functional. Why is that? I would assume it's the same driver which is used?

I'm using this from the JSON output to detect if a command port (and which) is available for the modem attached, but unfortunately that doesn't work any more.

Can this be fixed easily? Or is there an alternate/better method maybe?
