STTY(1)								       STTY(1)

NAME
       stty - set terminal options

SYNOPSIS
       stty [ option ... ]

DESCRIPTION
       Stty  sets  certain I/O options on the current output terminal, placing
       its output on the diagnostic output.  With no argument, it reports  the
       speed  of  the  terminal	 and  the  settings  of	 the options which are
       different from their defaults.  Use of one  of  the  following  options
       modifies the output as described:

       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).
