.SH NAME
termcap \- terminal capability data base
.SH SYNOPSIS
.B /etc/termcap
.SH DESCRIPTION
.B Termcap\^
is a data base describing terminals,
used,
.IR e.g. ,
by
.BR vi\^ (1)
and
.BR curses\^ (3).
Terminals are described in
.B termcap\^
by giving a set of capabilities that they have and by describing
how operations are performed.
Padding requirements and initialization sequences
are included in
.BR termcap\^ .
.PP
Entries in
.B termcap\^
consist of a number of `:'-separated fields.
The first entry for each terminal gives the names that are known for the
terminal, separated by `|' characters.
The first name is always two characters
long and is used by older systems which store the terminal type
in a 16-bit word in a system-wide data base.
The second name given is the most common abbreviation for the terminal,
the last name given should be a long name fully identifying the terminal,
and all others are understood as synonyms for the terminal name.
All names but the first and last
should be in lower case and contain no blanks;
the last name may well contain
upper case and blanks for readability.
.PP
Terminal names (except for the last, verbose entry)
should be chosen using the following conventions.
The particular piece of hardware making up the terminal
should have a root name chosen, thus \*(lqhp2621\*(rq.
This name should not contain hyphens.
Modes that the hardware can be in
or user preferences
should be indicated by appending a hyphen and an indicator of the mode.
Therefore, a \*(lqvt100\*(rq in 132-column mode would be \*(lqvt100-w\*(rq.
The following suffixes should be used where possible:
.sp
.ta
.if t .ta \w'\fBSuffix\fP\ \ \ 'u +\w'With automatic margins (usually default)\ \ 'u
.if n .ta \w'Suffix\ \ \ 'u +\w'With automatic margins (usually default)\ \ 'u
.nf
.if t .nr Xx \n(.lu-\n(.i-\w'\fBSuffix\fP\ \ \ With automatic margins (usually default)\ \ vt100-am'u
.if t .in +\n(Xxu/2u
\fBSuffix	Meaning	Example\fP
-w	Wide mode (more than 80 columns)	vt100-w
-am	With automatic margins (usually default)	vt100-am
-nam	Without automatic margins	vt100-nam
-\fIn\fP	Number of lines on the screen	aaa-60
-na	No arrow keys (leave them in local)	concept100-na
-\fIn\^\fPp	Number of pages of memory	concept100-4p
-rv	Reverse video	concept100-rv
.fi
.SH CAPABILITIES
.PP
The characters in the
.B Notes
field in the table have the following meanings
(more than one may apply to a capability):
.PP
.ta
.ta \w'N\ \ \ 'u
.nr fi \w'N\ \ \ '
.in +\n(fiu
.ti -\n(fiu
N	indicates numeric parameter(s)
.ti -\n(fiu
P	indicates that padding may be specified
.ti -\n(fiu
*	indicates that padding may be based on the number of lines affected
.ti -\n(fiu
o	indicates capability is obsolete
.in +\n(fiu
.PP
\*(lqObsolete\*(rq capabilities have no
.B terminfo\^
equivalents,
since they were considered useless,
or are subsumed by other capabilities.
New software should not rely on them at all.
