- .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
- .b P* .
