RUTM50 and USB to Serial adapter

I see prior forum posts like this reporting success using USB/Serial adapters on the USB A port of RUT955 and RUT956 routers to get additional serial ports.

Can I expect the same with the new RUTM50? Would adding such an adapter make Serial IP and MODBUS features available in RUTM50 firmware, like they are for RUT956?

Hello,

This feature should be present on the RUTM50, as it is already available on the RUTX50, and they are almost identical devices. When the serial cable is plugged in, a new selectable device should become available. Additionally, Modbus and other services are enabled on devices without serial by default.

Kind regards,
