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.

       -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.

       prints  baud  rate, line discipline, and deviations from stty sane.  In
       settings, CHAR is taken literally, or coded as in  ^c,  0x37,  0177  or
