_\bS_\bt_\bt_\by sets certain I/O options on the current output termi-
nal, placing its output on the diagnostic output. With no
argument, it reports the speed of the terminal and the set-
tings of the options which are different from their
defaults. Use of one of the following options modifies the
output as described:
a\bal\bll\bl All normally used option settings are reported.
e\bev\bve\ber\bry\byt\bth\bhi\bin\bng\bg
Everything _\bs_\bt_\bt_\by knows about is printed.
s\bsp\bpe\bee\bed\bd The terminal speed alone is printed on the stan-
dard output.
s\bsi\biz\bze\be The terminal (window) sizes are printed on the
standard output, first rows and then columns.
The option strings are selected from the following
set:
e\bev\bve\ben\bn allow even parity input
-\b-e\bev\bve\ben\bn disallow even parity input
o\bod\bdd\bd allow odd parity input
-\b-o\bod\bdd\bd disallow odd parity input
r\bra\baw\bw raw mode input (n\bno\bo input processing (erase, kill,
interrupt, ...); parity bit passed back)
-\b-r\bra\baw\bw negate raw mode
c\bco\boo\bok\bke\bed\bd same as `-raw'
c\bcb\bbr\bre\bea\bak\bk make each character available to _\br_\be_\ba_\bd(2) as
received; no erase and kill processing, but all
other processing (interrupt, suspend, ...) is per-
formed
-\b-c\bcb\bbr\bre\bea\bak\bk make characters available to _\br_\be_\ba_\bd only when new-
line is received
-\b-n\bnl\bl allow carriage return for new-line, and output
CR-LF for carriage return or new-line
n\bnl\bl accept only new-line to end lines
e\bec\bch\bho\bo echo back every character typed
-\b-e\bec\bch\bho\bo do not echo characters
l\blc\bca\bas\bse\be map upper case to lower case
-\b-l\blc\bca\bas\bse\be do not map case
t\bta\ban\bnd\bde\bem\bm 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

input
-\b-t\bta\ban\bnd\bde\bem\bm disable flow control
-\b-t\bta\bab\bbs\bs replace tabs by spaces when printing
t\bta\bab\bbs\bs preserve tabs
e\bek\bk set erase and kill characters to # and @
For the following commands which take a character argument
_\bc, you may also specify _\bc 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.
e\ber\bra\bas\bse\be _\bc set erase character to _\bc (default `#', but often
reset to ^H.)
k\bki\bil\bll\bl _\bc set kill character to _\bc (default `@', but often
reset to ^U.)
i\bin\bnt\btr\br _\bc set interrupt character to _\bc (default DEL or ^?
(delete), but often reset to ^C.)
q\bqu\bui\bit\bt _\bc set quit character to _\bc (default control \.)
s\bst\bta\bar\brt\bt _\bc set start character to _\bc (default control Q.)
s\bst\bto\bop\bp _\bc set stop character to _\bc (default control S.)
e\beo\bof\bf _\bc set end of file character to _\bc (default control
D.)
b\bbr\brk\bk _\bc set break character to _\bc (default undefined.) This
character is an additional character causing
wakeup.

Set terminal baud rate to the number given, if
possible. (These are the speeds supported by the
DH-11 interface).
r\bro\bow\bws\bs _\bn The terminal size is recorded as having _\bn rows.
c\bco\bol\blu\bum\bmn\bns\bs _\bn The terminal size is recorded as having _\bn columns.
c\bco\bol\bls\bs _\bn is an alias for _\bc_\bo_\bl_\bu_\bm_\bn_\bs.
A teletype driver which supports the job control processing
of _\bc_\bs_\bh(1) and more functionality than the basic driver is
fully described in _\bt_\bt_\by(4). The following options apply only
to it.
n\bne\bew\bw Use new driver (switching flushes typeahead).
c\bcr\brt\bt Set options for a CRT (crtbs, ctlecho and, if >=
1200 baud, crterase and crtkill.)
c\bcr\brt\btb\bbs\bs Echo backspaces on erase characters.
p\bpr\brt\bte\ber\bra\bas\bse\be For printing terminal echo erased characters back-
wards within ``\'' and ``/''.
c\bcr\brt\bte\ber\bra\bas\bse\be Wipe out erased characters with ``backspace-
space-backspace.''
-\b-c\bcr\brt\bte\ber\bra\bas\bse\be Leave erased characters visible; just backspace.
c\bcr\brt\btk\bki\bil\bll\bl Wipe out input on like kill ala c\bcr\brt\bte\ber\bra\bas\bse\be.\b.
-\b-c\bcr\brt\btk\bki\bil\bll\bl Just echo line kill character and a newline on
line kill.
c\bct\btl\ble\bec\bch\bho\bo Echo control characters as ``^_\bx'' (and delete as
``^?''.) Print two backspaces following the EOT
character (control D).
-\b-c\bct\btl\ble\bec\bch\bho\bo Control characters echo as themselves; in cooked
mode EOT (control-D) is not echoed.
d\bde\bec\bcc\bct\btl\blq\bq After output is suspended (normally by ^S), only a
start character (normally ^Q) will restart it.
This is compatible with DEC's vendor supplied sys-
tems.
-\b-d\bde\bec\bcc\bct\btl\blq\bq After output is suspended, any character typed
will restart it; the start character will restart
output without providing any input. (This is the
default.)
t\bto\bos\bst\bto\bop\bp Background jobs stop if they attempt terminal out-
put.
-\b-t\bto\bos\bst\bto\bop\bp Output from background jobs to the terminal is
allowed.
t\bti\bil\bld\bde\be Convert ``~'' to ```'' on output (for Hazeltine
terminals).
-\b-t\bti\bil\bld\bde\be Leave poor ``~'' alone.

-\b-f\bfl\blu\bus\bsh\bho\bo Output is not being discarded.
p\bpe\ben\bnd\bdi\bin\bn 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).
-\b-p\bpe\ben\bnd\bdi\bin\bn Input is not pending.
p\bpa\bas\bss\bs8\b8 Passes all 8 bits through on input, in any mode.
-\b-p\bpa\bas\bss\bs8\b8 Strips the 0200 bit on input except in raw mode.
m\bmd\bdm\bmb\bbu\buf\bf Start/stop output on carrier transitions (not
implemented).
-\b-m\bmd\bdm\bmb\bbu\buf\bf Return error if write attempted after carrier
drops.
l\bli\bit\bto\bou\but\bt Send output characters without any processing.
-\b-l\bli\bit\bto\bou\but\bt Do normal output processing, inserting delays,
etc.
n\bno\boh\bha\ban\bng\bg Don't send hangup signal if carrier drops.
-\b-n\bno\boh\bha\ban\bng\bg Send hangup signal to control process group when
carrier drops.
e\bet\btx\bxa\bac\bck\bk Diablo style etx/ack handshaking (not imple-
mented).
The following special characters are applicable only to the
new teletype driver and are not normally changed.
s\bsu\bus\bsp\bp _\bc set suspend process character to _\bc (default con-
trol Z).
d\bds\bsu\bus\bsp\bp _\bc set delayed suspend process character to _\bc
