Define/Update Variable Table (Esc - s)
The Define/Update Variable Table (Esc - s) sequence allows you to
define the terminal’s video and data attributes by setting attribute
parameter values in the Variable Field Definitions table. This sequence
also allows the resetting of the Variable Field Definitions Table back to
its initial (default) values. The following is the format of the Esc - s
sequence:
Esc -
p1
;
p2
;
p3
s
p4
[[
p4
...
where:
- is the ASCII minus sign (2Dh)
; is the ASCII semicolon (3Bh)
s is the ASCII lowercase s (73h)
If
p1
= 0 (30h), a specified range of up to 32 values is modified,
(96 ASCII characters). For example, the sequence
Esc - 0 ; 1 ; 5 s
modifies the first five lines of the Variable Field Definitions table.
