NAME

       ModemManager - mobile broadband modem management daemon

SYNOPSIS

       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

       --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.

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.
