Return:
ES:BP = specified pointer CX = bytes/character of on-screen font (not the requested font!) DL = highest character row on screen
Note: For UltraVision v2+, the 9xN alternate fonts follow the corresponding 8xN font at ES:BP+256N
BUG: The IBM EGA and some other EGA cards return in DL the number of rows on screen rather than the highest row number (which is one less).
