NAME
       stty - change and print terminal line settings
SYNOPSIS
       stty [-F DEVICE | --file=DEVICE] [SETTING]...
       stty [-F DEVICE | --file=DEVICE] [-a|--all]
       stty [-F DEVICE | --file=DEVICE] [-g|--save]
DESCRIPTION
       Print or change terminal characteristics.
       Mandatory  arguments  to  long  options are mandatory for short options
       too.
       -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
       --version
              output version information and exit
       Optional - before SETTING indicates negation.   An  *  marks  non-POSIX
       settings.  The underlying system defines which settings are available.
