The "DM" port is a QCDM capable ttyUSBX. If you want to know which one
it is, run under ModemManager, and check which of the ports is flagged
as "qcdm" in the list of ports shown in "mmcli -m 0" output; then stop
ModemManager and you can run that tool on the tty directly (Dan should
have more details about what the tool does, I really never played with
it).
