ModemManager [OPTION...]

DESCRIPTION
       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.

APPLICATION OPTIONS
       --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.

LOGGING OPTIONS
       --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.

TEST OPTIONS
       --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.
