F33_TEXT_CURSOR (AX
=
OOOAH)
This function defines either a software text cursor, or what the hardware text cursor looks like.
The parameter in BX selects the cursor type. When BX equals one, the hardware cursor is
defined. When BX equals 0, the software cursor is selected. If the hardware cursor is selected,
then the parameters in
ex
and DX define the first and last scan line of the hardware cursor. If
the software cursor is selected, then
ex
defines the AND mask for the character and attribute
bytes. DX defines the new character and attribute bytes.
