SYNOPSIS
       ModemManager [--version] | [--help]

       ModemManager [--debug] [--log-level=<level>] [--log-file=<filename>] [--timestamps] [--relative-timestamps]

DESCRIPTION
       The ModemManager daemon provides a unified high level API for communicating with (mobile broadband) modems. While the basic commands are standardized, the more advanced operations (like signal qual‐
       ity monitoring while connected) varies a lot.

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

OPTIONS
       The following options are supported:

       --version
              Print the ModemManager software version and exit.

       --help Print ModemManager's available options and exit.

       --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.

       --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.

       --timestamps
              Include absolute timestamps in the log output.

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