OpenBSD-7.1beta EM7455 with default ports config detects as umb0 without AT ports

Hi list,

Just connected EM7455 modem (factory default port configuration with MBIM + AT port + NMEA port + DM port) to a machine with latest 7.1beta snapshot.

The modem detected as umb0, but no AT port or NMEA port detected at all.

How did developers implement any alternative mechanism to access AT command port and NMEA port to obtain GPS data from modem?
