NAME
stty - set the options for a terminal
USAGE
stty [ -a ] [ -g ] [ options ]
DESCRIPTION
Stty sets certain terminal I/O options for the device that
is the current standard input. Without arguments, it
reports the settings of certain options. With the -a argu-
ment, it reports all of the option settings; with the -g
argument, it reports current settings in a form that can be
used as an argument to another stty command.
Detailed information about the modes listed in the first
five groups below may be found in termio (7).
The options listed under COMBINATION MODE OPTIONS are imple-
mented using options in the previous groups. Note that many
combinations of options make no sense, but stty does no san-
ity checking.
CONTROL MODE OPTIONS

parodd (-parodd)
Select odd (even) parity.

presentation.
echo (-echo)
Not supported in DOMAIN/IX. Echo back (do not
echo back) every character typed.
echoe (-echoe)
Echo (do not echo) the ERASE character as a
backspace-space-backspace string. Note: this mode
erases the ERASEed character on many CRT termi-
nals; however, it does not keep track of column
position and, as a result, may be confusing on
escaped characters, tabs, and backspaces.
echok (-echok)
Echo (do not echo) NL after the KILL character.
lfkc (-lfkc)
Same as echok (-echok); this option is obsolete.
echonl (-echonl)
Echo (do not echo) NL.

stwrap (-stwrap)

79 characters on a synchronous line.
stflush (-stflush)

chronous line.
CONTROL ASSIGNMENT OPTIONS
control character c
Set control character to c, where control charac-
ter is erase, kill, intr, quit, swtch, eof, ctab,
min, or time. Ctab is used with -stappl. Min and
time are used with -icanon. If c is preceded by a
caret (^) to escape the Shell, then the value of
the corresponding CTRL character is used. A
``^?'' is interpreted as DEL and ``^-'' is inter-
preted as undefined.
line i Not supported in DOMAIN/IX.

KILL, INTR, QUIT, SWTCH, EOT, or output postpro-
cessing).

(-raw or cooked) options are immediately effective. All
other settings are remembered for use when a window is run-
ning under control of a VT100 emulator.
