.B \-litout
Does normal output processing, such as inserting delays.
.TP
.B autoflow
Causes the terminal multiplexer to automatically respond to start and stop
characters.  This functionality is only provided if the stop character is 
.CT S
and the start character is <CTRL/Q>.
.TP
.B \-autoflow
Uses software controlled flow control.
.TP
.B nohang
Does not send a hangup signal if the carrier drops.
Note that the 
.B nohang
option should be used carefully.  For example, suppose that you have
the
.PN nohang
option in your .login file and are logged in over a modem.  If the
carrier drops, the next call in on this line gets your active
shell.
.TP
.B \-nohang
Sends a hangup signal to control process group when carrier drops.
.TP
.B pass8
Allows full eight bit ascii characters in input and output.
.TP
.B \-pass8
Strips characters to seven bits, thus disallowing the use of eight bit
ascii characters.
.sp
.PP
The following special characters are applicable only 
when the line discipline is set to NTTYDISC.  They
are not normally changed.  The 
.PN stty
.B new
option sets the line discipline to NTTYDISC.
.TP 15
.BI susp \ c\fR
Sets the suspend process character to \fIc\fR.
The default is <CTRL/Z>.
.TP
.BI dsusp \ c\fR
Sets the delayed suspend process character to \fIc\fR.
The default is <CTRL/Y>.
.TP
.BI rprnt \ c\fR
Sets the reprint line character to \fIc\fR.
The default is <CTRL/R>.
.TP
.BI flush \ c\fR
Sets the flush output character to \fIc\fR.
The default is <CTRL/O>.
.TP
.BI werase \ c\fR
Sets the word erase character to \fIc\fR.
The default is <CTRL/W>.
.TP
.BI lnext \ c\fR
Sets the literal next character to \fIc\fR.
The default is <CTRL/V>.
.TP
.BI quote \ c\fR
Sets the quote character (for erase and kill) to \fIc\fR.
The default is <CTRL/\\>.
.sp
.SH Termio Operation
This section describes the arguments and options that are used when
the terminal line is set to the termio line discipline (TERMIODISC).  The
termio line discipline is intended for programs that use either IEEE P1003
termios, or System Five style termio.  Unless noted otherwise, all options in
this section are applicable to both IEEE P1003 termios or System Five termio.
.PP
With no arguments, 
.B stty
reports the speed of the terminal and the
settings of certain options.
.sp
.TP 5
.B \-a
Reports option settings relevant to System Five termios.
.TP
.B \-p
Reports option settings relevant to IEEE POSIX termios.
.PP
For more information about the modes listed in the first five groups below
refer to 
.MS termio 4
and
.MS termios 4 . 
.sp

.I "control-character c"
Sets

to
.IR c ,
where
.I control-character
is
.BR erase ", " kill ", " intr ,
.BR quit ", " eof ", " eol ,
.BR min ", or " time
.BR ( min " and " time
are used with
.BR \-icanon ".
.PP
The following control characters are applicable to POSIX mode only:
.BR susp ", " dsusp ", " rprnt ,
.BR flush ", " werase ", " lnext ", 
.BR quote.
.PP
If
.I c\^
is preceded by a circumflex
.RB ( ^ ),
then the value used is the corresponding 
.B CTRL 
character (for example, ^d is a 
.B CTRL-d );
^? is interpreted as DEL and ^\-  is interpreted as undefined.
.PP
The
.B new

sets the line discipline to NTTYDISC.  Note that this changes the line 
discipline to be a non-termio line discipline.  Once this has been done
the
.PN stty
