attstty(1) DG/UX 4.30 attstty(1)
NAME
att_stty - set the options for a terminal
SYNOPSIS
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.

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.

hang up (do not hang up) Dataphone connection on

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)
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)
Licensed material--property of copyright holder(s) Page 2
attstty(1) DG/UX 4.30 attstty(1)
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)
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)
Licensed material--property of copyright holder(s) Page 3
attstty(1) DG/UX 4.30 attstty(1)
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)
preserve (expand to spaces) tabs when printing.
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.
