This is a test from freshly booted modem, MM not running:

I don't think there is much MM can do here.  This modem firmware does
not work properly with QMAP muxing.  Sorry about the confusion I've
caused by assuming this would work.

Unless I am missing something in the sequence above?

I'll switch the firmware to MBIM and see how that goes.  I hear it's the
future anyway :-)
