attstty Command

SYNTAX
attstty [ -a ] [ -g ] [ options ]
DESCRIPTION
att_stty is the AT & T version of the stty command. It can be
invoked directly using att_stty or indirectly using stty while in
line discipline 0.
att_stty sets certain terminal I/O options for the device that is
the current standard input; without arguments, it reports the
settings of certain options.
In this report, if a character is preceded by a caret (^), then
the value of that option is the corresponding CTRL character
(e.g., ``^h'' is CTRL-h ; in this case, recall that CTRL-h is the
same as the ``back-space'' key.) The sequence ``^''' means that
an option has a null value. For example, normally attstty -a
will report that the value of swtch is ``^'''; however, if shl
(1) has been invoked, attstty -a will have the value ``^z''.
-a reports all of the option settings;
-g reports current settings in a form that can be used as an
argument to another att_stty command.
Options in the combination mode are implemented using options in
the previous mode groups. The modes are discussed in the
following paragraphs. Note that many combinations of options
make no sense, but no sanity checking is performed. The options
are selected from the following:
Control Modes
parenb (-parenb)
enable (disable) parity generation and detection.
parodd (-parodd)
select odd (even) parity.
cs5 cs6 cs7 cs8
select character size (see termio(7)).
0 hang up phone line immediately.

110 300 600 1200 1800 2400 4800 9600 19200 38400
Set terminal baud rate to the number given, if
possible. All speeds are not supported by all hardware
interfaces. For example. baud rates 50, 75, and 200
are not supported and return an error message.
hupcl (-hupcl)
hang up (do not hang up) Dataphone connection on last
close.
hup (-hup)
same as hupcl (-hupcl).
cstopb (-cstopb)
use two (one) stop bits per character.
cread (-cread)
enable (disable) the receiver.
clocal (-clocal)
assume a line without (with) modem control.
loblk (-loblk)
block (do not block) output from a non-current layer.
Input Modes
ignbrk (-ignbrk)
ignore (do not ignore) break on input.
brkint (-brkint)
signal (do not signal) INTR on break.
ignpar (-ignpar)
ignore (do not ignore) parity errors.
parmrk (-parmrk)
mark (do not mark) parity errors (see termio(7)).
inpck (-inpck)
enable (disable) input parity checking.
istrip (-istrip)
strip (do not strip) input characters to seven bits.
inlcr (-inlcr)
map (do not map) NL to CR on input.
igncr (-igncr)
ignore (do not ignore) CR on input.
icrnl (-icrnl)
map (do not map) CR to NL on input.
iuclc (-iuclc)
map (do not map) upper-case alphabetics to lower case
on input.
ixon (-ixon)
enable (disable) START/STOP output control. Output is
stopped by sending an ASCII DC3 and started by sending
an ASCII DC1.
ixany (-ixany)
allow any character (only DC1) to restart output.
ixoff (-ixoff)

attstty(1)
request that the system send (not send) START/STOP
characters when the input queue is nearly empty/full.
Output Modes
opost (-opost)
post-process output (do not post-process output; ignore
all other output modes).
olcuc (-olcuc)
map (do not map) lower-case alphabetics to upper case
on output.
onlcr (-onlcr)
map (do not map) NL to CR-NL on output.
ocrnl (-ocrnl)
map (do not map) CR to NL on output.
onocr (-onocr)
do not (do) output CRs at column zero.
onlret (-onlret)
on the terminal NL performs (does not perform) the CR
function.
ofill (-ofill)
use fill characters (use timing) for delays.
ofdel (-ofdel)
fill characters are DELs (NULs).
cr0 cr1 cr2 cr3
select style of delay for carriage returns (see
termio(7)).
nl0 nl1 select style of delay for line-feeds (see termio(7)).
tab0 tab1 tab2 tab3
select style of delay for horizontal tabs (see
termio(7)).
bs0 bs1 select style of delay for backspaces (see termio(7)).
ff0 ff1 select style of delay for form-feeds (see termio(7)).
vt0 vt1 select style of delay for vertical tabs (see
termio(7)).
Local Modes
isig (-isig)
enable (disable) the checking of characters against the
special control characters INTR, QUIT, and SWTCH.
icanon (-icanon)
enable (disable) canonical input (ERASE and KILL
processing).
xcase (-xcase)
canonical (unprocessed) upper/lower-case presentation.
echo (-echo)

attstty(1)
echo back (do not echo back) every character typed.
echoe (-echoe)
echo (do not echo) ERASE character as a backspace-
space-backspace string. Note: this mode will erase the
ERASEed character on many CRT terminals; however, it
does not keep track of column position and, as a
result, may be confusing on escaped characters, tabs,
and backspaces.
echok (-echok)
echo (do not echo) NL after KILL character.
lfkc (-lfkc)
the same as echok (-echok); obsolete.
echonl (-echonl)
echo (do not echo) NL.
noflsh (-noflsh)
disable (enable) flush after INTR, QUIT, or SWTCH.
Control Assignments
control-character c
set control-character to c, where control-character is
erase, kill, intr, quit, swtch, eof, min, or time (min
and time are used with -icanon; see termio(7)). The
values for min and time are stored in the locations
used for eof and eol, respectively. A change in min
will be printed as a change in eof. Similarly, a
change in time will be printed as change in eol. If c
is preceded by a (escaped from the shell) caret (^),
then the value used is the corresponding CTRL character
(e.g., ``^d'' is a CTRL-d); ``^?'' is interpreted as
DEL and ``^-'' is interpreted as undefined.
line i set line discipline to i (0 < i < 127 ). DG/UX
implements only 0 and 1. Other numbers will return an
error.
Combination Modes
evenp or parity
enable parenb and cs7.
oddp enable parenb, cs7, and parodd.
-parity, -evenp, or -oddp
disable parenb, and set cs8.
raw (-raw or cooked)
enable (disable) raw input and output (no ERASE, KILL,
INTR, QUIT, SWTCH, EOT, or output post processing).
nl (-nl) unset (set) icrnl, onlcr. In addition -nl unsets
inlcr, igncr, ocrnl, and onlret.

lcase (-lcase)
set (unset) xcase, iuclc, and olcuc.
LCASE (-LCASE)
same as lcase (-lcase).
tabs (-tabs or tab3)

ek reset ERASE and KILL characters back to normal # and @.
sane resets all modes to some reasonable values.
term set all modes suitable for the terminal type term,
where term is one of tty33, tty37, vt05, tn300, ti700,
or tek.
