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 sepa-
       rately 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 exten-
       sions, however.	There are more Minix specific flags that match the Minix specific attributes described in tty(4).
