31: .sh 2 Disclaimer
32: .pp
33: The description of terminals is a difficult business,
34: and we only attempt to summarize the capabilities here:
35: for a full description see
36: .b termcap (5).
37: .sh 2 Overview
38: .pp
39: Capabilities from
40: .b termcap
41: are of three kinds:
42: string valued options,
43: numeric valued options,
44: and boolean options.
45: The string valued options are the most complicated,
46: since they may include padding information,
47: which we describe now.
48: .pp
49: Intelligent terminals often require padding on intelligent operations
50: at high (and sometimes even low) speed.
51: This is specified by a number before the string in the capability,
52: and has meaning for the capabilities which have a
53: .b P
54: at the front of their comment.
55: This normally is a number of milliseconds to pad the operation.
56: In the current system which has no true programmable delays,
57: we do this by sending a sequence of pad characters
58: (normally nulls, but can be changed
59: (specified by
60: .i PC )).
61: In some cases, the pad is better computed as some number of milliseconds
62: times the number of affected lines
63: (to the bottom of the screen usually,
64: except when terminals have insert modes which will shift several lines.)
65: This is specified as,
66: i e.g. ,
67: .b 12* .
68: before the capability,
69: to say 12 milliseconds per affected whatever
70: (currently always line).
71: Capabilities where this makes sense say
72: .b P* .
