ModemManager - mobile broadband modem management daemon

--filter-policy=<policy>
              Specify which ports are probed and how:

                'ALLOWLIST-ONLY'
                       Only devices or ports explicitly allowlisted with the 'ID_MM_DEVICE_PROCESS' udev tag are
                       probed.

                'STRICT'
                       Only the TTY ports that are heuristically determined to be very likely to be modem  ports
                       are probed. Nay end up ignoring some devices.

       --no-auto-scan
              Fully disable udev-based auto-scan looking for devices.

       --initial-kernel-events=<filename>
              Specify  location  of  the  file  where  the  list  of  initial  kernel  events  is available. The
              ModemManager daemon will process this file on startup.

       --debug
              Runs ModemManager with "DEBUG" log level and without daemonizing. This is useful for debugging, as
              it directs log output to the controlling terminal in addition to syslog.

       -V,--version
              Print the ModemManager software version and exit.

       -h,--help
              Show application options.

       ModemManager provides a unified high level API for communicating with mobile broadband modems, regardless
       of  the  protocol  used to communicate with the actual device (Generic AT, vendor-specific AT, QCDM, QMI,
       MBIM...).

       ModemManager is a DBus-based system daemon and is not meant to be used directly from the command line.

--log-level=<level>
              Sets how much information ModemManager sends to the log  destination  (usually  syslog's  "daemon"
              facility).  By  default,  only  informational, warning, and error messages are logged. Given level
              must be one of "ERR", "WARN", "INFO" or "DEBUG".

       --log-file=<filename>
              Specify location of the file where ModemManager will dump its log messages, instead of syslog.

       --log-journal
              Output log message to the systemd journal.

       --log-timestamps
              Include absolute timestamps in the log output.

       --log-relative-timestamps
              Include timestamps, relative to the start time of the daemon, in the log output.

ModemManager [OPTION...]

--test-session
              Run the ModemManager daemon in the Session bus instead of the System bus.

       --test-enable
              Enable the Test DBus interface in the daemon.

       --test-plugin-dir=[PATH]
              Specify an alternate directory where the daemon should look for vendor plugins.
