STTY(1V) — USER COMMANDS
NAME
stty − set or alter the options for a terminal
SYNOPSIS
stty [ −ag ] [ option ] ...
SYSTEM V SYNOPSIS
/usr/5bin/stty [ −ag ] [ option ] ...
DESCRIPTION
stty sets certain terminal I/O options for the device that is the current standard output. Without arguments, it reports the settings of certain terminal options for the device that is the standard output; the settings are reported on the standard error.
Detailed information about the modes listed in the first five groups below may be found in termio(4). Options in the last group are implemented using options in the previous groups. Note: many combinations of options make no sense, but no sanity checking is performed.
SYSTEM V DESCRIPTION
stty sets or reports terminal options for the device that is the current standard input; the settings are reported on the standard output.
OPTIONS
−a Report all of the option settings.
−g Report current settings in a form that can be used as an argument to another stty command.
Special Requests
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.
size and speed always report on the settings of /dev/tty, and always report the settings to the standard output.

Control Assignments
control-character c
Set control-character to c, where control-character is one of erase, kill, intr, quit, eof, eol, eol2, start, stop, susp, rprnt, flush, werase, or lnext. If c is preceded by a caret (^), (escaped from the shell) then the value used is the corresponding CTRL character (for instance, ‘^D’ is a CTRL-D); ‘^?’ is interpreted as DEL and ‘^−’ is interpreted as undefined.
min i Set the MIN value to i.
time i Set the TIME value to i.
rows n Set the recorded number of rows on the terminal to i.
columns i Set the recorded number of columns on the terminal to i.
cols i An alias for columns i.
Combination Modes
cooked Process the ERASE, WERASE, KILL, INTR, QUIT, EOF, EOL, EOL2, STOP, START, SUSP, RPRNT, FLUSH, and LNEXT, characters specially, and perform output post-processing.
evenp or parity
Enable parenb and cs7.
oddp Enable parenb, cs7, and parodd.
−parity, −evenp, or −oddp
Disable parenb, and set cs8.
[−]raw Enable raw input and output. With a ‘−’, disable raw I/O. In raw mode, there is no special processing of the ERASE, WERASE, KILL, INTR, QUIT, EOF, EOL, EOL2, STOP, START, SUSP, RPRNT, FLUSH, nor LNEXT characters, nor is there any output post-processing.
[−]nl Unset icrnl, onlcr. With a ‘−’, set them. In addition −nl unsets inlcr, igncr, ocrnl, and onlret.
[−]lcase Set xcase, iuclc, and olcuc. With a ‘−’, unset them.
[−]LCASE Same as lcase (−lcase).
[−]tabs
tab3 Preserve TAB characters when printing. With a ‘−’, or with tab3, expand TAB characters to SPACE characters.
ek Reset the ERASE and KILL characters back to normal: DEL and CTRL-U).
sane Reset all modes to some reasonable values.
crt Set options for a CRT (echoe, echoctl, and, if >= 1200 baud, echoke.)
dec Set all modes suitable for Digital Equipment Corp. operating systems users (ERASE, KILL, and INTR characters to ^?, ^U, and ^C, decctlq, and crt.)
term Set all modes suitable for the terminal type term, where term is one of tty33, tty37, vt05, tn300, ti700, or tek.
