How to trace the communication with the modem?

I am trying to debug the reset sequence of my modem (I've posted today
a separate message about this).

I was wondering if there is a way to trace the communication between
MM and the device, or perhaps between libqmi or the device to output
the content and translation of the QMI messages (or whatever is used
to talk to the modem)?
