DESCRIPTION
|
||
Stty shows or changes the parameters of the terminal connected to
|
||
standard input. Stty takes a myriad of arguments most of which are
|
||
mapped directly to the flags and special characters described in tty(4),
|
||
so we won't describe them here.
|
||
|
||
Stty has three forms of operation. First, without any arguments stty
|
||
shows all terminal attributes that are different from the default state.
|
||
Option -a makes stty print all terminal attributes, and -g lets stty
|
||
print the attributes in a special encoded form, a simple row of colon
|
||
separated hexadecimal numbers.
|
||
|
||
In the second form of operation stty takes an encoded form as produced by
|
||
the -g option and sets the terminals attributes to its decoded value.
|
||
|
||
In the third form stty interprets a series of flags and parameters
|
||
settings and modifies the terminal attributes accordingly. Flags can be
|
||
given as icanon or -icanon for instance, either setting or clearing the
|
||
ICANON flag. Special character values can by set like intr=^C for
|
||
example, which sets the interrupt character to CTRL-C. You can either
|
||
use a real CTRL-C, or the two characters `^' and `C'. In any case it is
|
||
probably necessary to use quotes to guard it from the shell: intr='^C'.
|
||
|
||
A number alone is interpreted as a baud rate setting for both the input
|
||
and output rate. The input or the output rate can be set separately with
|
||
use of the ispeed and ospeed prefixes to the number. The character size
|
||
can be set with cs5, cs6, cs7 or cs8.
|
||
|
||
The MIN and TIME value, and the number of rows and columns of the window
|
||
can also be set using one of the keywords min, time, rows or cols,
|
||
followed by a decimal number that is the value of the setting.

|
||
|
||
|
||
Stty accepts several keywords that are not named by corresponding flags
|
||
or parameters in tty(4). They set several attributes at once:
|
||
|
||
cooked
|
||
Same as icrnl ixon opost onlcr isig icanon iexten echo, setting all
|
||
the attributes that are needed for line oriented mode.
|
||
|
||
raw Same as -icrnl -ixon -opost -onlcr -isig -icanon -iexten -echo,
|
||
setting all the attributes for a raw data channel.
|
||
|
||
evenp parity
|
||
These synonyms are equal to cs7 parenb -parodd, setting the line to
|
||
7 bits even parity.
|
||
|
||
oddp Same as cs7 parenb parodd, setting the line to 7 bits odd parity.
|
||
|
||
-parity -evenp -oddp
|
||
All synonyms for cs8 -parenb, setting the line to 8 bits, no parity.
|
||
|
||
nl Same as icrnl, setting carriage return to line feed input
|
||
translation.
|
||
|
||
-nl Same as -icrnl -inlcr -igncr, disabling any carriage return or line
|
||
feed handling.
|
||
|
||
ek Set the ERASE and KILL special characters back to the default.
|
||
|
||
sane Set all attributes to the default except things like the line speed
|
||
and parity, because their "sane" value is probably what it is right
|
||
now. The default values are compiled into stty from the <termios.h>
|
||
include file. Use stty sane; stty -a to know what they are.
|
||
|
||
FILES
|
||
|
||
/etc/ttytab The init field of this file may contain an stty command to
|
||
set the attributes to match an attached RS232 terminal or
|
||
modem.
|
||
|
||
SEE ALSO
|
||
tty(4), ttytab(5).
|
||
|
||
NOTES
|
||
The cooked, raw, rows and cols keywords are Minix additions beyond the
|
||
keywords defined by POSIX. Rows and cols are common UNIX extensions,
|
||
however. There are more Minix specific flags that match the Minix
|
||
specific attributes described in tty(4).
