Carriage return for OSD when in TEXTSET mode
OSD equivalent of delete to end of row (DER)
Establishes a TEXT type of OSD display
Establishes a pop-on type of OSD display
OSD equivalent of pop-on caption end of caption (EOC)
OSD equivalent of erase displayed memory
OSD equivalent of erase non-displayed memory
Sets display row and moves cursor to char column 1. The low order nibble of rr
designates the display row. Bit 5 of rr specifies a Double High row. For example: rr =
0Eh would select display row 14. rr = 23h would select display row three, Double
High.
Sets the physical row, where the low order nibble of rr designates the physical row.
rr can be any value from 00h to 0Fh.
Places the cursor at the character column position designated by cc, which can be
any value from 00h to 20h (column 0-32). Zero is the PAC space.
Writes the data byte dd to the current cursor location and then increments the cursor.
Maps the current physical row to the display row designated by the low nibble of the
rr byte. Bit 4 of rr = 1 enables display of the row. Bit 5 of rr = 1 indicates a Double
High row.
Same as A3 command but specifies a Double Wide character.
