stty - set terminal options
SYNOPSIS
stty [ option ... ]
DESCRIPTION
Stty sets certain I/O options on the current output terminal. With no argument, it reports the current settings of the options. The
option strings are selected from the following set:
even allow even parity
-even disallow even parity
odd allow odd parity
-odd disallow odd parity
raw raw mode input (no erase, kill, interrupt, quit, EOT; 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
-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
-tabs replace tabs by spaces when printing
tabs preserve tabs
ek reset erase and kill characters back to normal # and @
erase c set erase character to c. C can be of the form `^X' which is interpreted as a `control X'.
kill c set kill character to c. `^X' works here also.
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
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
hup hang up dataphone on last close.
-hup do not hang up dataphone on last close.
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).

stty - change and print terminal line settings
SYNOPSIS
stty [-F DEVICE | --file=DEVICE] [SETTING]...
stty [-F DEVICE | --file=DEVICE] [-a|--all]
stty [-F DEVICE | --file=DEVICE] [-g|--save]
DESCRIPTION
Print or change terminal characteristics.
-a, --all
print all current settings in human-readable form
-g, --save
print all current settings in a stty-readable form
-F, --file=DEVICE
open and use the specified DEVICE instead of stdin
--help display this help and exit
--version
output version information and exit
Optional - before SETTING indicates negation. An * marks non-POSIX settings. The underlying system defines which settings are available.
Special characters:
* dsusp CHAR
CHAR will send a terminal stop signal once input flushed
eof CHAR
CHAR will send an end of file (terminate the input)

CHAR will end the line
* eol2 CHAR
alternate CHAR for ending the line
erase CHAR
CHAR will erase the last character typed
intr CHAR
CHAR will send an interrupt signal
kill CHAR
CHAR will erase the current line
* lnext CHAR
CHAR will enter the next character quoted
quit CHAR
CHAR will send a quit signal
* rprnt CHAR
CHAR will redraw the current line
start CHAR
CHAR will restart the output after stopping it
stop CHAR
CHAR will stop the output

CHAR will send a terminal stop signal

CHAR will switch to a different shell layer
* werase CHAR
CHAR will erase the last word typed
Special settings:
N set the input and output speeds to N bauds
