       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.

       * rows N
	      tell the kernel that the terminal has N rows

       Handle  the  tty	 line connected to standard input.  Without arguments,
       prints baud rate, line discipline, and deviations from stty  sane.   In
       settings,  CHAR	is  taken  literally, or coded as in ^c, 0x37, 0177 or
       127; special values ^- or undef used to disable special characters.
