ESC [ @ n1 n2 m1 m2 m3 m4
Selects single or double-high mode, single or double-wide mode, and single or double line feeds.
The two bytes
n1
and
n2
specify how many mode bytes (
m1
,
m2
,
m3
,
m4
) follow. Theoretically, there
may be
n1
+ (
n2
x 256) mode bytes. Actually,
n2
must be 0, and
n1
may be 0 to 4, but is normally 4.
m1
and
m2
must be 0 (NUL).
m3
and
m4
may be set to the values in the following tables.
m3
hex
