DESCRIPTION</H2><PRE>
+<H2>
<a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
<STRONG>Tset</STRONG> initializes terminals. <STRONG>Tset</STRONG> first determines the
type of terminal that you are using. This determination
is done as follows, using the first terminal type found.
3. (BSD systems only.) The terminal type associated with
the standard error output device in the <EM>/etc/ttys</EM> file.
- (On Linux and System-V-like UNIXes, <EM>getty</EM> does this job by
- setting <STRONG>TERM</STRONG> according to the type passed to it by
- <EM>/etc/inittab</EM>.)
+ (On System-V-like UNIXes and systems using that conven-
+ tion, <EM>getty</EM> does this job by setting <STRONG>TERM</STRONG> according to the

- 4. The default terminal type, ``unknown''.

If the terminal type was not specified on the command-
- line, the -m option mappings are then applied (see below
- for more information). Then, if the terminal type begins
- with a question mark (``?''), the user is prompted for
- confirmation of the terminal type. An empty response con-
- firms the type, or, another type can be entered to specify
- a new type. Once the terminal type has been determined,
- the terminfo entry for the terminal is retrieved. If no
- terminfo entry is found for the type, the user is prompted
- for another terminal type.

+ found for the type, the user is prompted for another ter-
+ minal type.
+
+ Once the terminfo entry is retrieved, the window size,
+ backspace, interrupt and line kill characters (among many
other things) are set and the terminal and tab initializa-
- tion strings are sent to the standard error output.
- Finally, if the erase, interrupt and line kill characters
- have changed, or are not set to their default values,

+ Finally, if the erase, interrupt and line kill characters

+ Use the <STRONG>-c</STRONG> or <STRONG>-w</STRONG> option to select only the window sizing
+ versus the other initialization. If neither option is
+ given, both are assumed.

turns off cbreak and raw modes, turns on newline transla-
The options are as follows:
- -q The terminal type is displayed to the standard out-

- The option `-' by itself is equivalent but archaic.
+ <STRONG>-c</STRONG> Set control characters and modes.
- -e Set the erase character to <EM>ch</EM>.
+ <STRONG>-e</STRONG> Set the erase character to <EM>ch</EM>.
- -I Do not send the terminal or tab initialization
+ <STRONG>-I</STRONG> Do not send the terminal or tab initialization
strings to the terminal.
- -Q Don't display any values for the erase, interrupt and
- line kill characters.
+ <STRONG>-i</STRONG> Set the interrupt character to <EM>ch</EM>.
- <STRONG>-V</STRONG> reports the version of ncurses which was used in this
- program, and exits.
+ <STRONG>-k</STRONG> Set the line kill character to <EM>ch</EM>.
- -i Set the interrupt character to <EM>ch</EM>.
+ <STRONG>-m</STRONG> Specify a mapping from a port type to a terminal.
+ See the section <STRONG>TERMINAL</STRONG> <STRONG>TYPE</STRONG> <STRONG>MAPPING</STRONG> for more infor-
+ mation.
- -k Set the line kill character to <EM>ch</EM>.
+ <STRONG>-Q</STRONG> Do not display any values for the erase, interrupt
+ and line kill characters. Normally <STRONG>tset</STRONG> displays the
+ values for control characters which differ from the
+ system's default values.
- -m Specify a mapping from a port type to a terminal.
- See below for more information.
+ <STRONG>-q</STRONG> The terminal type is displayed to the standard out-
+ put, and the terminal is not initialized in any way.
+ The option `-' by itself is equivalent but archaic.

- The arguments for the -e, -i, and -k options may either be
- entered as actual characters or by using the `hat' nota-
- tion, i.e. control-h may be specified as ``^H'' or ``^h''.
+ <STRONG>-V</STRONG> reports the version of ncurses which was used in this
+ program, and exits.
+

and the <EM>terminal</EM> argument in some historic implementations
of <STRONG>tset</STRONG> has been removed.
