   Global options:

       -h --help

              This help

       --config [~/]<path to config file>

              Give  a config file to use. If it starts with '~/', path is at home dir.  Each line in config file
              is one option, '-' or '--' must not be given!  Default: '~/.osmocom/cnetz/fuvst.conf'

       --no-config

              Even if a config file exists, don't use it.

       -v --verbose <level> | <level>,<category>[,<category>[,...]] | list

              Use 'list' to get a list of all levels and  categories.   Verbose  level:  digit  of  debug  level
              (default  =  '3')  Verbose level+category: level digit followed by one or more categories -> If no
              category is specified, all categories are selected

       -e --echo-test

              Use  echo  test,  to  send  back  audio  from  mobile  phone's microphone to the speaker. (German:
              'Blasprobe').

       -c --call-device hw:<card>,<device>[/hw:<card>.<rec-device>]

              Sound card and device number for headset (default = '') You  may  specify  a  different  recording
              device by using '/'.

              Disable built-in call control and offer socket

       --cc "<osmo-cc arg>" [--cc ...]

              Pass arguments to Osmo-CC endpoint. Use '-cc help' for description.

       --no-l16

       -C --bs-config <filename>

              Give DKO config file (6 KBytes tape file) to be loaded at boot time.

       station_id: Give 7 or 8 digits of station ID,

              so you don't need to enter it for every start of this application.   Give  7  digits  for  regular
              number  format.   Give  8 digits for extended number format.  You may use '0161xxxxxxx' as prefix.
              You may use '0161xxxxxxxx' as prefix.  You  may  use  '+49161xxxxxxx'  as  prefix.   You  may  use
              '+49161xxxxxxxx' as prefix.

       Press  digits  '0'..'9' and then 'd' key to dial towards mobile station.  Press 'h' key to hangup.  Press
       'w' key to toggle display of RX wave form.  Press 'c' key to toggle display of channel status.  Press 'm'
       key to toggle display of measurement value.

                                                                                                        fuvst(1)
