Terminal names (except for the last, verbose entry) should be chosen
- using the following conventions. The particular piece of hardware mak-
- ing up the terminal should have a root name, thus "hp2621". This name
- should not contain hyphens. Modes that the hardware can be in, or user
- preferences, should be indicated by appending a hyphen and a mode suf-
- fix. Thus, a vt100 in 132-column mode would be vt100-w. The following
- suffixes should be used where possible:
-
- <STRONG>Suffix</STRONG> <STRONG>Meaning</STRONG> <STRONG>Example</STRONG>
- -<EM>nn</EM> Number of lines on the screen aaa-60
- -<EM>n</EM>p Number of pages of memory c100-4p

- -m Mono mode; suppress color ansi-m

- each line of the table,
-
- The <STRONG>variable</STRONG> is the name by which the programmer (at the terminfo
- level) accesses the capability.
-
- The <STRONG>capname</STRONG> is the short name used in the text of the database, and is
- used by a person updating the database. Whenever possible, capnames
- are chosen to be the same as or similar to the ANSI X3.64-1979 standard
- (now superseded by ECMA-48, which uses identical or very similar
- names). Semantics are also intended to match those of the specifica-
- tion.
-
- The termcap code is the old <STRONG>termcap</STRONG> capability name (some capabilities
- are new, and have names which termcap did not originate).
-
- Capability names have no hard length limit, but an informal limit of 5
- characters has been adopted to keep them short and to allow the tabs in
- the source file <STRONG>Caps</STRONG> to line up nicely.
-
- Finally, the description field attempts to convey the semantics of the
- capability. You may find some codes in the description field:
-
- (P) indicates that padding may be specified
-
- #[1-9] in the description field indicates that the string is passed
- through tparm with parms as given (#<EM>i</EM>).
-
- (P*) indicates that padding may vary in proportion to the number of
- lines affected
-
- (#<EM>i</EM>) indicates the <EM>i</EM>th parameter.

- The XSI Curses standard added these hardcopy capabilities. They were
- used in some post-4.1 versions of System V curses, e.g., Solaris 2.5
- and IRIX 6.x. Except for <STRONG>YI</STRONG>, the <STRONG>ncurses</STRONG> termcap names for them are
- invented. According to the XSI Curses standard, they have no termcap
- names. If your compiled terminfo entries use these, they may not be
- binary-compatible with System V terminfo entries after SVr4.1; beware!

+ SVr4 (and X/Open Curses) list several string capabilities for setting
+ margins. Two were intended for use with terminals, and another six
+ were intended for use with printers.
+
+ <STRONG>o</STRONG> The two terminal capabilities assume that the terminal may have the
+ capability of setting the left and/or right margin at the current
+ cursor column position.
+
+ <STRONG>o</STRONG> The printer capabilities assume that the printer may have two types
+ of capability:
+
+ <STRONG>o</STRONG> the ability to set a top and/or bottom margin using the current
+ line position, and
+
+ <STRONG>o</STRONG> parameterized capabilities for setting the top, bottom, left,
+ right margins given the number of rows or columns.
+
+ In practice, the categorization into "terminal" and "printer" is not
+ suitable:
+
+ <STRONG>o</STRONG> The AT&T SVr4 terminal database uses <STRONG>smgl</STRONG> four times, for AT&T
+ hardware.
+
+ Three of the four are printers. They lack the ability to set
+ left/right margins by specifying the column.
+
+ <STRONG>o</STRONG> Other (non-AT&T) terminals may support margins but using different
+ assumptions from AT&T.
+
+ For instance, the DEC VT420 supports left/right margins, but only
+ using a column parameter. As an added complication, the VT420 uses
+ two settings to fully enable left/right margins (left/right margin
+ mode, and origin mode). The former enables the margins, which
+ causes printed text to wrap within margins, but the latter is
+ needed to prevent cursor-addressing outside those margins.
+
+ <STRONG>o</STRONG> Both DEC VT420 left/right margins are set with a single control
+ sequence. If either is omitted, the corresponding margin is set to
+ the left or right edge of the display (rather than leaving the
+ margin unmodified).
+
+ These are the margin-related capabilities:
+
+ <STRONG>Name</STRONG> <STRONG>Description</STRONG>
+ ---------------------------------------------------
+ <STRONG>smgl</STRONG> Set left margin at current column
+ <STRONG>smgr</STRONG> Set right margin at current column

+ <STRONG>smgtb</STRONG> Set both top and bottom margins to <EM>T</EM> and <EM>B</EM>
+
+ When writing an application that uses these string capabilities, the
+ pairs should be first checked to see if each capability in the pair is
+ set or only one is set:
+
+ <STRONG>o</STRONG> If both <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> are set, each is used with a single
+ argument, <EM>N</EM>, that gives the column number of the left and right
+ margin, respectively.
+
+ <STRONG>o</STRONG> If both <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> are set, each is used to set the top and
+ bottom margin, respectively:
+
+ <STRONG>o</STRONG> <STRONG>smgtp</STRONG> is used with a single argument, <EM>N</EM>, the line number of the
+ top margin.
+
+ <STRONG>o</STRONG> <STRONG>smgbp</STRONG> is used with two arguments, <EM>N</EM> and <EM>M</EM>, that give the line
+ number of the bottom margin, the first counting from the top of
+ the page and the second counting from the bottom. This
+ accommodates the two styles of specifying the bottom margin in
+ different manufacturers' printers.
+
+ When designing a terminfo entry for a printer that has a settable
+ bottom margin, only the first or second argument should be used,
+ depending on the printer. When developing an application that uses
+ <STRONG>smgbp</STRONG> to set the bottom margin, both arguments must be given.
+
+ Conversely, when only one capability in the pair is set:
+
+ <STRONG>o</STRONG> If only one of <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> is set, then it is used with two
+ arguments, the column number of the left and right margins, in that
+ order.
+
+ <STRONG>o</STRONG> Likewise, if only one of <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG> is set, then it is used
+ with two arguments that give the top and bottom margins, in that
+ order, counting from the top of the page.
+
+ When designing a terminfo entry for a printer that requires setting
+ both left and right or top and bottom margins simultaneously, only
+ one capability in the pairs <STRONG>smglp</STRONG> and <STRONG>smgrp</STRONG> or <STRONG>smgtp</STRONG> and <STRONG>smgbp</STRONG>
+ should be defined, leaving the other unset.
+
+ Except for very old terminal descriptions, e.g., those developed for

+ improved set of capabilities was added late in the SVr4 releases (<STRONG>smglr</STRONG>
+ and <STRONG>smgtb</STRONG>), which explicitly use two parameters for setting the

+
+ When setting margins, the line- and column-values are zero-based.

- There are two basic kinds of intelligent terminals with respect to

You can determine the kind of terminal you have by clearing the screen
and then typing text separated by cursor motions. Type "abc def"
shift rigidly and characters to fall off the end, then your terminal
does not distinguish between blanks and untyped positions. If the
"abc" shifts over to the "def" which then move together around the end

If your terminal has one or more kinds of display attributes, these can
be represented in a number of different ways. You should choose one
display form as <EM>standout</EM> <EM>mode</EM>, representing a good, high contrast,
If there is a sequence to set arbitrary combinations of modes, this
should be given as <STRONG>sgr</STRONG> (set attributes), taking 9 parameters. Each

We begin each escape sequence by turning off any existing modes, since
