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
+ type passed to it by <EM>/etc/inittab</EM>.)
- 4. The default terminal type, ``unknown''.

If the terminal type was not specified on the command-
- line, the <STRONG>-m</STRONG> 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.

+ 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.

+ versus the other initialization. If neither option is
+ given, both are assumed.
When invoked as <STRONG>reset</STRONG>, <STRONG>tset</STRONG> sets cooked and echo modes,
turns off cbreak and raw modes, turns on newline transla-
The options are as follows:
- <STRONG>-q</STRONG> The terminal type is displayed to the standard out-

- The option `-' by itself is equivalent but archaic.

<STRONG>-e</STRONG> Set the erase character to <EM>ch</EM>.
<STRONG>-I</STRONG> Do not send the terminal or tab initialization
strings to the terminal.
- <STRONG>-Q</STRONG> Don't display any values for the erase, interrupt and
- line kill characters.
-
- <STRONG>-V</STRONG> reports the version of ncurses which was used in this
- program, and exits.
-
<STRONG>-i</STRONG> Set the interrupt character to <EM>ch</EM>.
<STRONG>-k</STRONG> Set the line kill character to <EM>ch</EM>.

SETTING THE ENVIRONMENT</H2><PRE>

<a name="h2-SETTING-THE-ENVIRONMENT">SETTING THE ENVIRONMENT</a></H2><PRE>
It is often desirable to enter the terminal type and
information about the terminal's capabilities into the
shell's environment. This is done using the <STRONG>-s</STRONG> option.
When the <STRONG>-s</STRONG> option is specified, the commands to enter the
information into the shell's environment are written to
the standard output. If the <STRONG>SHELL</STRONG> environmental variable
- ends in ``csh'', the commands are for <STRONG>csh</STRONG>, otherwise, they

are for <STRONG>sh</STRONG>. Note, the <STRONG>csh</STRONG> commands set and unset the
shell variable <STRONG>noglob</STRONG>, leaving it unset. The following
line in the <STRONG>.login</STRONG> or <STRONG>.profile</STRONG> files will initialize the
eval `tset -s options ... `

TERMINAL TYPE MAPPING</H2><PRE>

<a name="h2-TERMINAL-TYPE-MAPPING">TERMINAL TYPE MAPPING</a></H2><PRE>
When the terminal is not hardwired into the system (or the
current system information is incorrect) the terminal type
derived from the <EM>/etc/ttys</EM> file or the <STRONG>TERM</STRONG> environmental
terminal used on such ports.
The purpose of the <STRONG>-m</STRONG> option is to map from some set of
- conditions to a terminal type, that is, to tell <STRONG>tset</STRONG> ``If
+ conditions to a terminal type, that is, to tell <STRONG>tset</STRONG> "If
I'm on this port at a particular speed, guess that I'm on
- that kind of terminal''.
+ that kind of terminal".
The argument to the <STRONG>-m</STRONG> option consists of an optional port
- type, an optional operator, an optional baud rate
- specification, an optional colon (``:'') character and a
- terminal type. The port type is a string (delimited by
- either the operator or the colon character). The operator
- may be any combination of ``>'', ``<'', ``@'', and ``!'';
- ``>'' means greater than, ``<'' means less than, ``@''
- means equal to and ``!'' inverts the sense of the test.

- with the speed of the standard error output (which should
- be the control terminal). The terminal type is a string.
+ type, an optional operator, an optional baud rate specifi-
+ cation, an optional colon (":") character and a terminal

If the terminal type is not specified on the command line,
- the <STRONG>-m</STRONG> mappings are applied to the terminal type. If the
- port type and baud rate match the mapping, the terminal
- type specified in the mapping replaces the current type.
- If more than one mapping is specified, the first applica-

+ port type and baud rate match the mapping, the terminal

+ If more than one mapping is specified, the first applica-
ble mapping is used.
- For example, consider the following mapping:
+ For example, consider the following mapping:
<STRONG>dialup>9600:vt100</STRONG>. The port type is dialup , the operator

be used.
If no baud rate is specified, the terminal type will match
any baud rate. If no port type is specified, the terminal

+ type will match any port type. For example, <STRONG>-m</STRONG>
<STRONG>dialup:vt100</STRONG> <STRONG>-m</STRONG> <STRONG>:?xterm</STRONG> will cause any dialup port,
regardless of baud rate, to match the terminal type vt100,
- and any non-dialup port type to match the terminal type
- ?xterm. Note, because of the leading question mark, the

- it is suggested that the entire <STRONG>-m</STRONG> option argument be
- placed within single quote characters, and that <STRONG>csh</STRONG> users
- insert a backslash character (``\'') before any exclama-
