Double-height line sequences make the cursor line the top or bottom half of a
double-height, double-width line. The computer ignores these sequences. Double-
width line makes the line with the cursor double-width, single-height. The
computer ignores this sequence as well. The computer does support the single-
width line.
Erasure Mode
Erasure mode (ERM) determines whether erasing functions (ECH, erase character;
EL, erase in line; and ED, erase in display) can edit protected characters. The
following table lists erasure mode sequences.
The following table lists the erasing and editing functions that ERM affects. ERM
also affects the independent style of character protection.
