stty - (BSD) set the options for a terminal /usr/ucb/stty [-a] [-g] [-h] [options] Stty sets certain I/O options on the current terminal. With no argument, it reports the current settings of selected options; the -a flag causes it to report all options. With the -g flag, stty prints all settings in a form that can be passed to it again to restore the current settings. The -h flag prints a table of all control characters in addition to the output given with -a .

Special option values recognized only if given as single argument are:

12 all Print the normal output followed by a control character table.

12 everything Same as -h .

12 speed Print the speed rate.

12 size Print the rows and columns of the terminal.

If either -g , speed or size are given, stty uses /dev/tty to get the terminal settings, otherwise, the standard output is used.

The option strings are selected from the following set; where an option is shown prefixed by `[-]', it can be negated as described in the text.

Control modes:

[-]parenb enable (disable) parity bits

[-]parodd select odd (even) parity

50 75 110 134 150 200 300 600 1200 1800 2400 4800 9600

(not all terminals support all rates).

[-]onlcr (do not) map NL to CR

[-]onocr (do not) ignore CR

[-]onlret NL is (not) return

[-]ofill (do not) use fill characters

[-]ofdel fill character is DEL (NUL)

bs0 bs1 select style of delay for backspace

vt0 bt1 select style of delay for vertical tab

Local modes:

[-]isig

enable (disable) intr, quit, and susp processing

[-]icanon enable (disable) erase and kill processing

[-]cbreak same as -icanon

[-]xcase (no) canonical case presentation

[-]echo (do not) echo every character typed

[-]echoe (do not) echo erase character as `^H ^H'

[-]crterase same as echoe

[-]echok (do not) echo NL after kill character

[-]lfkc same as echok

[-]echonl (do not) echo NL regardless of echo

[-]noflsh (do not) flush after intr, quit, and susp

[-]tostop send SIGTTOU for background output

[-]echoctl

(no) visual representation of control characters

[-]ctlecho same as echoctl

[-]echoprt (do not) echo erased characters

[-]prterase same as echoprt

[-]echoke

(do not) print `^H ^H' sequences at line erase

[-]crtkill same as echoke

[-]pendin (do not) retype pending input

[-]iexten

Control characters:

intr c set intr character to c.

quit c set quit character to c.

erase c set erase character to c.

kill c set kill character to c.

eof c set eof character to c.

eol c set eol character to c.

eol2 c set eol2 character to c.

swtch c set swtch character to c.

start c set start character to c.

stop c set stop character to c.

susp c set susp character to c.

dsusp c set dsusp character to c.

rprnt c set rprnt character to c.

flush c set flush character to c.

werase c set werase character to c.

lnext c set lnext character to c.

A control character may be either given as a literal character, or as `^c' for ASCII control characters CTRL-c; the special values `^-' and `undef' disable the control function. Multibyte characters cannot be used as control characters; trying to do so will result in the control character set to the first byte of the multibyte character sequence, which has the undesired effect of applying the control function to more characters than the one supplied.

Combination modes et cetera:

[-]raw

(i.\|e. no erase, kill, interrupt, quit, EOT; parity bit passed back)

as received; no erase and kill

(make characters available to read

only when newline is received)
