STTY

NAME

SYNOPSIS

DESCRIPTION

all

All normally used option settings are reported.

everything

Everything stty knows about is printed.

speed

The terminal speed alone is printed on the standard 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 read(2) as received; no erase and kill processing, but all other processing (interrupt, suspend, ...) is performed

-cbreak

make characters available to read only when newline 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 @

-extproc

process characters external to the terminal driver. This option is used when there is a loss of characters or improper handling of special characters (e.g., carriage returns and line feeds) during a telnet(1C) session from a non-NEXTSTEP local host to a NEXTSTEP remote host.

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 ioctl(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 Corporation Model 33 terminal.

tty37

set all modes suitable for the Teletype Corporation Model 37 terminal.

vt05

set all modes suitable for Digital Equipment Corp. VT05 terminal

dec

set all modes suitable for Digital Equipment Corp. operating systems users; (erase, kill, and interrupt characters to ^?, ^U, and ^C, decctlq and ``newcrt''.)

tn300

set all modes suitable for a General Electric TermiNet 300

ti700

set all modes suitable for Texas Instruments 700 series terminal

tek

set all modes suitable for Tektronix 4014 terminal

0

hang up phone line immediately

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 columns.

A teletype driver which supports the job control processing of csh(1) and more functionality than the basic driver is fully described in tty(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 backwards 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 systems.

-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 output.

-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 implemented).

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 control 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).
