Double-High Mode			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.
