That is not a stupid question :-)

No, I do not have a command line proposal.  You can always manually
stich the request together, but you would have to manually parse the
response as well and that is extremely hard in this case given that it
contains a number of complex TLVs.


Well, OK, we can try.  Sending the command:

 perl -e 'print pack("C*", map { hex }, qw/01 10 00 00 01 01 00 04 00 2c 00 04 00 01 01 00 00/)' >/dev/cdc-wdm0
                                                          ^^

Where CID=1 is reused from the one pre-allocated by qmi-network.  I got
it from /tmp/qmi-network-state. You may need to use another value.  But
using qmicli to allocate it saves you from doing that manually.

Then you need to read the response. hexdump will do line buffering so you
don't get everything, but this should be enough:

 hexdump -C /dev/cdc-wdm0

My APN is "pilot.telenor", which you can recongnize in the above.  The
number of the default profile is missing though.  You can see the start
of the profile name ("profile"), but the number is missing.  Repeat the
request a couple of times if you need the whole output (you will the get
multiple responses of course, and all but the last one will be complete).
