stty - set the options for a terminal
/usr/ucb/stty [ -a ] [
-g ] [ -h ] [ modes ]
SUNWscpu
stty sets certain
terminal I/O
options for the device that is the current standard output;
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 (for example, ‘‘^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.
- -a
- Report all of the option settings.
- -g
- Report current settings in a form that can be used as an argument to
another stty command.
- -h
- Report all the option settings with the control
characters in an easy to read column format.
Options in the last group are
implemented using options in the previous groups. Note: Many combinations
of options make no sense, but no sanity checking is performed. Hardware
flow control and clock modes options may not be supported by all hardware
interfaces. The options are selected from the following:
- all
- Reports the same option settings as stty without arguments, but with the
control characters in column format.
- everything
- Everything stty knows about
is printed. Same as -h option.
- speed
- The terminal speed alone is reported
on the standard output.
- size
- The terminal (window) sizes are printed on
the standard output, first rows and then columns. This option is only appropriate
if currently running a window system.
- size
- and speed always report on the
settings of /dev/tty, and always report the settings to the standard output.
