.sh 1 "Capabilities from termcap" 1
|
|
.sh 2 Disclaimer
|
|
.pp
|
|
The description of terminals is a difficult business,
|
|
and we only attempt to summarize the capabilities here:
|
|
for a full description see
|
|
.b termcap (5).
|
|
.sh 2 Overview
|
|
.pp
|
|
Capabilities from
|
|
.b termcap
|
|
are of three kinds:
|
|
string valued options,
|
|
numeric valued options,
|
|
and boolean options.
|
|
The string valued options are the most complicated,
|
|
since they may include padding information,
|
|
which we describe now.
|
|
.pp
|
|
Intelligent terminals often require padding on intelligent operations
|
|
at high (and sometimes even low) speed.
|
|
This is specified by a number before the string in the capability,
|
|
and has meaning for the capabilities which have a
|
|
.b P
|
|
at the front of their comment.
|
|
This normally is a number of milliseconds to pad the operation.
|
|
In the current system which has no true programmable delays,
|
|
we do this by sending a sequence of pad characters
|
|
(normally nulls, but can be changed
|
|
(specified by
|
|
.i PC )).
|
|
In some cases, the pad is better computed as some number of milliseconds
|
|
times the number of affected lines
|
|
(to the bottom of the screen usually,
|
|
except when terminals have insert modes which will shift several lines.)
|
|
This is specified as,
|
|
i e.g. ,
|
|
.b 12* .
|
|
before the capability,
|
|
to say 12 milliseconds per affected whatever
|
|
(currently always line).
|
|
Capabilities where this makes sense say
|
|
