SYNTAX
berkstty [ option ... ]
DESCRIPTION
berk_stty is the Berkeley version of the stty command. It can be
invoked directly using berk_stty or indirectly using stty while
in line discipline 1.
Berk_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. With the
argument ``all'', all normally used option settings are reported.
With the argument ``everything'', everything berk_stty knows
about is printed. 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 @
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 extra wakeup causing character.

ioctl(2))
nl0 nl1 nl2 nl3

tab0 tab1 tab2 tab3

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.
intrup Send a signal (SIGTINT) to the terminal control process
group whenever an input record (line in cooked mode,
character in cbreak or raw mode) is available for
reading.
-intrup Don't send input available interrupts.
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).
