NAME
stty - set terminal options
SYNOPSIS
stty [ option ... ]
DESCRIPTION
_S_t_t_y sets certain I/O options on the current output termi-
nal, placing its output on the diagnostic output. With no
argument, it reports the speed of the terminal and the set-
tings of the options which are different from their
defaults. Use of one of the following options modifies the
output as described:
all All normally used option settings are reported.
everything
Everything _s_t_t_y knows about is printed.
x Everything _s_t_t_y knows about is printed.
speed The terminal speed alone is printed on the stan-
dard output.
size The terminal (window) sizes are printed on the
standard output, first rows and then columns.
The option strings are selected from the following
set:
even allow even parity input
-even disallow even parity input
odd allow odd parity input
-odd disallow odd parity input
raw raw mode input (no input processing (erase, kill,
interrupt, ...); parity bit passed back)
-raw negate raw mode
cooked same as `-raw'
cbreak make each character available to _r_e_a_d(2) as
received; no erase and kill processing, but all
other processing (interrupt, suspend, ...) is per-
formed
-cbreak make characters available to _r_e_a_d only when new-
line is received
-nl allow carriage return for new-line, and output
CR-LF for carriage return or new-line
nl accept only new-line to end lines
echo echo back every character typed
-echo do not echo characters
lcase map upper case to lower case
-lcase do not map case
tandem enable flow control, so that the system sends out

the stop character when its internal queue is in
danger of overflowing on input, and sends the
start character when it is ready to accept further
input
-tandem disable flow control
-tabs replace tabs by spaces when printing
tabs preserve tabs
ek set erase and kill characters to # and @
For the following commands which take a character argument
_c, you may also specify _c as the ``u'' or ``undef'', to set
the value to be undefined. A value of ``^x'', a 2 character
sequence, is also interpreted as a control character, with
``^?'' representing delete.
erase _c set erase character to _c (default `#', but often
reset to ^H.)
kill _c set kill character to _c (default `@', but often
reset to ^U.)
intr _c set interrupt character to _c (default DEL or ^?
(delete), but often reset to ^C.)
quit _c set quit character to _c (default control \.)
start _c set start character to _c (default control Q.)
stop _c set stop character to _c (default control S.)
eof _c set end of file character to _c (default control
D.)
brk _c set break character to _c (default undefined.) This
character is an additional character causing
wakeup.
cr0 cr1 cr2 cr3
select style of delay for carriage return (see
_i_o_c_t_l(2))
nl0 nl1 nl2 nl3
select style of delay for linefeed
tab0 tab1 tab2 tab3
select style of delay for tab
ff0 ff1 select style of delay for form feed
bs0 bs1 select style of delay for backspace
tty33 set all modes suitable for the Teletype Corpora-
tion Model 33 terminal.
tty37 set all modes suitable for the Teletype Corpora-
tion Model 37 terminal.
vt05 set all modes suitable for Digital Equipment Corp.

dec set all modes suitable for Digital Equipment Corp.

rupt characters to ^?, ^U, and ^C, decctlq and
``newcrt''.)
tn300 set all modes suitable for a General Electric Ter-
miNet 300
ti700 set all modes suitable for Texas Instruments 700

50 75 110 134 150 200 300 600 1200 1800 2400 4800 9600 exta extb
Set terminal baud rate to the number given, if
possible. (These are the speeds supported by the
DH-11 interface).
rows _n The terminal size is recorded as having _n rows.
columns _n The terminal size is recorded as having _n columns.
cols _n is an alias for _c_o_l_u_m_n_s.
A teletype driver which supports the job control processing
of _c_s_h(1) and more functionality than the basic driver is
fully described in _t_t_y(4). The following options apply only
to it.
new Use new driver (switching flushes typeahead).
crt Set options for a CRT (crtbs, ctlecho and, if >=
1200 baud, crterase and crtkill.)
crtbs Echo backspaces on erase characters.
prterase For printing terminal echo erased characters back-
wards within ``\'' and ``/''.
crterase Wipe out erased characters with ``backspace-
space-backspace.''
-crterase Leave erased characters visible; just backspace.
crtkill Wipe out input on like kill ala crterase.
-crtkill Just echo line kill character and a newline on
line kill.
ctlecho Echo control characters as ``^_x'' (and delete as
``^?''.) Print two backspaces following the EOT
character (control D).
-ctlecho Control characters echo as themselves; in cooked
mode EOT (control-D) is not echoed.
decctlq After output is suspended (normally by ^S), only a
start character (normally ^Q) will restart it.
This is compatible with DEC's vendor supplied sys-
tems.
-decctlq After output is suspended, any character typed
will restart it; the start character will restart
output without providing any input. (This is the
default.)
tostop Background jobs stop if they attempt terminal out-
put.
-tostop Output from background jobs to the terminal is
allowed.
tilde Convert ``~'' to ```'' on output (for Hazeltine
terminals).

-tilde Leave poor ``~'' alone.
flusho Output is being discarded usually because user hit
control O (internal state bit).
-flusho Output is not being discarded.
pendin Input is pending after a switch from cbreak to
cooked and will be re-input when a read becomes
pending or more input arrives (internal state
bit).
-pendin Input is not pending.
pass8 Passes all 8 bits through on input, in any mode.
-pass8 Strips the 0200 bit on input except in raw mode.
mdmbuf Start/stop output on carrier transitions (not
implemented).
-mdmbuf Return error if write attempted after carrier
drops.
litout Send output characters without any processing.
-litout Do normal output processing, inserting delays,
etc.
nohang Don't send hangup signal if carrier drops.
-nohang Send hangup signal to control process group when
carrier drops.
etxack Diablo style etx/ack handshaking (not imple-
mented).
The following special characters are applicable only to the
new teletype driver and are not normally changed.
susp _c set suspend process character to _c (default con-
trol Z).
dsusp _c set delayed suspend process character to _c
(default control Y).
rprnt _c set reprint line character to _c (default control
R).
flush _c set flush output character to _c (default control
O).
werase _c set word erase character to _c (default control W).
lnext _c set literal next character to _c (default control
V).
