.SH DESCRIPTION
.LP
The \fBstty\fR utility sets certain terminal I/O options for the device that is
the current standard input. Without arguments, \fBstty\fR reports the settings
of certain options.
.sp
.LP
In this report, if a character is preceded by a caret (\fB^\fR), then the value
of that option is the corresponding control character (for example, \fB^h\fR is
CTRL-h. In this case, recall that CTRL-h is the same as the BACKSPACE key). The
sequence \fB^@\fR means that an option has a null value.
.sp
.LP
See \fBtermio\fR(7I) for detailed information about the modes listed from
\fBControl\fR \fBModes\fR through \fBLocal Modes\fR. For detailed information
about the modes listed under \fBHardware\fR \fBFlow\fR \fBControl\fR
\fBModes\fR and \fBClock Modes\fR, see \fBtermiox\fR(7I).
.sp
.LP
Operands described in the \fBCombination Modes\fR section are implemented using
options in the earlier sections. Notice that many combinations of options make
no sense, but no sanity checking is performed. Hardware flow control and clock
modes options might not be supported by all hardware interfaces.
.SH OPTIONS
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-a\fR\fR
.ad
.RS 6n
Writes to standard output all of the option settings for the terminal.
.RE

.sp
.ne 2
.na
\fB\fB-g\fR\fR
.ad
.RS 6n
Reports current settings in a form that can be used as an argument to another
\fBstty\fR command. Emits termios-type output if the underlying driver supports
it. Otherwise, it emits termio-type output.

If \fIc\fR is a single character, the control character is set to that
character.
.sp
In the POSIX locale, if \fIc\fR is preceded by a caret (\fB^\fR) indicating an
escape from the shell and is one of those listed in the \fI^c\fR column of the
following table, then its value used (in the Value column) is the corresponding
control character (for example, ``\fB^d\fR'' is a CTRL-d). ``\fB^?\fR'' is
interpreted as DEL and ``\fB^\(mi\fR'' is interpreted as undefined.

.SH USAGE
.LP
The \fB-g\fR flag is designed to facilitate the saving and restoring of
terminal state from the shell level. For example, a program can:
.sp
.in +2
.nf
saveterm="$(stty -g)"      # save terminal state
stty (new settings)        # set new state
\&...                        # ...
stty $saveterm             # restore terminal state
.fi
.in -2
.sp

.sp
.LP
Since the \fB-a\fR format is so loosely specified, scripts that save and
restore terminal settings should use the \fB-g\fR option.
.SH ENVIRONMENT VARIABLES
.LP
See \fBenviron\fR(5) for descriptions of the following environment variables
that affect the execution of \fBstty\fR: \fBLANG\fR, \fBLC_ALL\fR,
\fBLC_CTYPE\fR, \fBLC_MESSAGES\fR, and \fBNLSPATH\fR.
.SH EXIT STATUS

.sp

.SH NOTES
.LP
Solaris does not support any of the actions implied by \fBswtch\fR, which was
used by the \fBsxt\fR driver on System V release 4. Solaris allows the
\fBswtch\fR value to be set, and prints it out if set, but it does not perform
the \fBswtch\fR action.
.sp
.LP
The job switch functionality on Solaris is actually handled by job control.
\fBsusp\fR is the correct setting for this.
