--------------------------------------------------------------------------------
INT 10h / AH = 0Eh - teletype output.
input:
AL = character to write.
This functions displays a character on the screen, advancing the cursor and scrolling the screen as necessary. The printing is always done to current active page.
--------------------------------------------------------------------------------
INT 10h / AH = 13h - write string.
input:
AL = write mode:
bit 0: update cursor after writing;
bit 1: string contains attributes.
BH = page number.
BL = attribute if string contains only characters (bit 1 of AL is zero).

--------V-101101-----------------------------
INT 10 - VIDEO - TEXT-MODE CHARGEN - LOAD ROM MONOCHROME PATTERNS (PS,EGA,VGA)
AX = 1101h
BL = block to load
Return: nothing
Notes: (see also AX=1100h)
This function will cause a mode set, completely resetting
the video environment, but without clearing the video buffer
the "monochrome" patters are 8x14 pixels in size
SeeAlso: AX=1100h,AX=1102h,AX=1103h,AX=1104h,AX=1111h,AH=1Bh,AX=CD10h

--------V-101103-----------------------------
INT 10 - VIDEO - TEXT-MODE CHARGEN - SET BLOCK SPECIFIER (PS,EGA,VGA)
AX = 1103h
BL = block specifier (see #00020)
Return: nothing
Notes: (see also AX=1110h)
This function allows dual character sets to appear on screen
simultaneously
SeeAlso: AX=1100h,AX=1101h,AX=1102h,AX=1104h,AH=1Bh,AX=CD10h
SeeAlso: MEM 0040h:0084h

Bitfields for block specifier:
Bit(s) Description (Table 00020)
---EGA/MCGA---
0,1 block selected by characters with attribute bit 3 clear
2,3 block selected by characters with attribute bit 3 set
---VGA---
0,1,4 block selected by characters with attribute bit 3 clear
2,3,5 block selected by characters with attribute bit 3 set
--------V-101120-----------------------------
INT 10 - VIDEO - GRAPH-MODE CHARGEN - SET USER 8x8 GRAPHICS CHARS (PS,EGA,VGA)
AX = 1120h
ES:BP -> user table for INT 1F
Return: nothing
Note: this function is meant to be called immediately after a mode set;
results are unpredictable at other times
SeeAlso: AX=1121h,AX=1122h,AX=1123h,AX=1124h,AX=1129h,INT 1F"SYSTEM DATA"

--------V-101130-----------------------------
INT 10 - VIDEO - GET FONT INFORMATION (EGA, MCGA, VGA)
AX = 1130h
BH = pointer specifier
00h INT 1Fh pointer
01h INT 43h pointer
02h ROM 8x14 character font pointer
03h ROM 8x8 double dot font pointer
04h ROM 8x8 double dot font (high 128 characters)
05h ROM alpha alternate (9 by 14) pointer (EGA,VGA)
06h ROM 8x16 font (MCGA, VGA)
07h ROM alternate 9x16 font (VGA only) (see #00021)
11h (UltraVision v2+) 8x20 font (VGA) or 8x19 font (autosync EGA)
12h (UltraVision v2+) 8x10 font (VGA) or 8x11 font (autosync EGA)
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).
