One of them is likely a QCDM port if this is really a Qualcomm based device. The other might be an inactive NMEA port. Serial doesn't necessarily imply AT commands... > Of the two responsive serial devices the first is the source of unsolicited > information such as a SIM insert.

Huawei use subclass+protocol to differentiate their vendor specific functions, so we usually get some idea of what to expect from the USB descriptors. Could you post the output of "lsusb -vd 03f0:9a1d", or the relevant part of /sys/kernel/debug/usb/devices? If this doesn't help, then the Windows drivers (if any?) should give some clue.
