- tialization strings. These strings are expected to set the terminal
- into modes consistent with the rest of the terminfo description. They
- are normally sent to the terminal, by the <EM>init</EM> option of the <STRONG>tput</STRONG> pro-
- gram, each time the user logs in. They will be printed in the follow-
- ing order:
+ A few capabilities are used only for tabs:
+
+ <STRONG>o</STRONG> If the terminal has hardware tabs, the command to advance to the
+ next tab stop can be given as <STRONG>ht</STRONG> (usually control/I).
+
+ <STRONG>o</STRONG> A "back-tab" command which moves leftward to the preceding tab stop
+ can be given as <STRONG>cbt</STRONG>.
+
+ By convention, if the teletype modes indicate that tabs are being
+ expanded by the computer rather than being sent to the terminal,
+ programs should not use <STRONG>ht</STRONG> or <STRONG>cbt</STRONG> even if they are present, since
+ the user may not have the tab stops properly set.
+
+ <STRONG>o</STRONG> If the terminal has hardware tabs which are initially set every <EM>n</EM>
+ spaces when the terminal is powered up, the numeric parameter <STRONG>it</STRONG> is
+ given, showing the number of spaces the tabs are set to.
+
+ The <STRONG>it</STRONG> capability is normally used by the <STRONG>tset</STRONG> command to determine
+ whether to set the mode for hardware tab expansion, and whether to
+ set the tab stops. If the terminal has tab stops that can be saved
+ in non-volatile memory, the terminfo description can assume that
+ they are properly set.
+
+ Other capabilities include
+
+ <STRONG>o</STRONG> <STRONG>is1</STRONG>, <STRONG>is2</STRONG>, and <STRONG>is3</STRONG>, initialization strings for the terminal,
+
+ <STRONG>o</STRONG> <STRONG>iprog</STRONG>, the path name of a program to be run to initialize the ter-
+ minal,
+
+ <STRONG>o</STRONG> and <STRONG>if</STRONG>, the name of a file containing long initialization strings.
+
+ These strings are expected to set the terminal into modes consistent
+ with the rest of the terminfo description. They are normally sent to
+ the terminal, by the <EM>init</EM> option of the <STRONG>tput</STRONG> program, each time the
+ user logs in. They will be printed in the following order:
run the program
<STRONG>iprog</STRONG>
- output <STRONG>is1</STRONG> <STRONG>is2</STRONG>
+ output
+ <STRONG>is1</STRONG> and
+ <STRONG>is2</STRONG>
set the margins using
- <STRONG>mgc</STRONG>, <STRONG>smgl</STRONG> and <STRONG>smgr</STRONG>
+ <STRONG>mgc</STRONG> or
+ <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> or
+ <STRONG>smgl</STRONG> and <STRONG>smgr</STRONG>

+ and finally output
+ <STRONG>is3</STRONG>.
Most initialization is done with <STRONG>is2</STRONG>. Special terminal modes can be
set up without duplicating strings by putting the common sequences in
A set of sequences that does a harder reset from a totally unknown
state can be given as <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG>, <STRONG>rf</STRONG> and <STRONG>rs3</STRONG>, analogous to <STRONG>is1</STRONG> <STRONG>,</STRONG> <STRONG>is2</STRONG> <STRONG>,</STRONG> <STRONG>if</STRONG>
- and <STRONG>is3</STRONG> respectively. These strings are output by the <STRONG>reset</STRONG> program,
- which is used when the terminal gets into a wedged state. Commands are
- normally placed in <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they produce annoying
- effects on the screen and are not necessary when logging in. For exam-
- ple, the command to set the vt100 into 80-column mode would normally be
- part of <STRONG>is2</STRONG>, but it causes an annoying glitch of the screen and is not
- normally needed since the terminal is usually already in 80 column
- mode.
+ and <STRONG>is3</STRONG> respectively. These strings are output by <EM>reset</EM> option of
+ <STRONG>tput</STRONG>, or by the <STRONG>reset</STRONG> program (an alias of <STRONG>tset</STRONG>), which is used when
+ the terminal gets into a wedged state. Commands are normally placed in
+ <STRONG>rs1</STRONG>, <STRONG>rs2</STRONG> <STRONG>rs3</STRONG> and <STRONG>rf</STRONG> only if they produce annoying effects on the screen

+ causes an annoying glitch of the screen and is not normally needed
+ since the terminal is usually already in 80-column mode.
The <STRONG>reset</STRONG> program writes strings including <STRONG>iprog</STRONG>, etc., in the same
order as the <EM>init</EM> program, using <STRONG>rs1</STRONG>, etc., instead of <STRONG>is1</STRONG>, etc. If
of every row). If a more complex sequence is needed to set the tabs
than can be described by this, the sequence can be placed in <STRONG>is2</STRONG> or <STRONG>if</STRONG>.
+ The <STRONG>tput</STRONG> <STRONG>reset</STRONG> command uses the same capability strings as the <STRONG>reset</STRONG>
+ command, although the two programs (<STRONG>tput</STRONG> and <STRONG>reset</STRONG>) provide different
+ command-line options.
+
+ In practice, these terminfo capabilities are not often used in initial-
+ ization of tabs (though they are required for the <STRONG>tabs</STRONG> program):
+
+ <STRONG>o</STRONG> Almost all hardware terminals (at least those which supported tabs)
+ initialized those to every <EM>eight</EM> columns:
+
+ The only exception was the AT&T 2300 series, which set tabs to
+ every <EM>five</EM> columns.
+
+ <STRONG>o</STRONG> In particular, developers of the hardware terminals which are com-
+ monly used as models for modern terminal emulators provided docu-
+ mentation demonstrating that <EM>eight</EM> columns were the standard.
+
+ <STRONG>o</STRONG> Because of this, the terminal initialization programs <STRONG>tput</STRONG> and <STRONG>tset</STRONG>
+ use the <STRONG>tbc</STRONG> (<STRONG>clear_all_tabs</STRONG>) and <STRONG>hts</STRONG> (<STRONG>set_tab</STRONG>) capabilities
+ directly only when the <STRONG>it</STRONG> (<STRONG>init_tabs</STRONG>) capability is set to a value
+ other than <EM>eight</EM>.
