       stty - change and print terminal line settings


       stty [-F DEVICE | --file=DEVICE] [SETTING]...
       stty [-F DEVICE | --file=DEVICE] [-a|--all]
       stty [-F DEVICE | --file=DEVICE] [-g|--save]


       Print or change terminal characteristics.

       -a, --all
              print all current settings in human-readable form

       -g, --save
              print all current settings in a stty-readable form

       -F, --file=DEVICE
              open and use the specified DEVICE instead of stdin

       --help display this help and exit

              output version information and exit

       Optional  -  before  SETTING  indicates negation.  An * marks non-POSIX
       settings.  The underlying system defines which settings are available.
