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

-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.

same as tab3
* vtN vertical tab delay style, N in [0..1]

Handle the tty line connected to standard input. Without arguments,
