All Interrupt for Emu8086(Assembly language)

The list of all interrupts that are currently supported by the emulator.
These interrupts should be compatible with IBM PC and all generations of x86,
original Intel 8086 and AMD compatible microprocessors, however Windows XP may
overwrite some of the original interrupts.
Quick reference:
the short list of supported interrupts with descriptions:

INT 10h / AH = 0 - set video mode.
input:
AL = desired video mode.
these video modes are supported:
00h - text mode. 40x25. 16 colors. 8 pages.
03h - text mode. 80x25. 16 colors. 8 pages.
13h - graphical mode. 40x25. 256 colors. 320x200 pixels. 1 page.
example:
mov al, 13h
mov ah, 0
int 10h

INT 10h / AH = 01h - set text-mode cursor shape.
input:
CH = cursor start line (bits 0-4) and options (bits 5-7).
CL = bottom cursor line (bits 0-4).

When bit 5 of CH is set to 0, the cursor is visible. when bit 5 is 1, the cursor is not
visible.
; hide blinking text cursor:
mov ch, 32
mov ah, 1
int 10h
; show standard blinking text cursor:
mov ch, 6
mov cl, 7
mov ah, 1
int 10h
; show box-shaped blinking text cursor:
mov ch, 0
mov cl, 7
mov ah, 1
int 10h
; note: some bioses required CL to be >=7,
; otherwise wrong cursor shapes are displayed.

INT 10h / AH = 2 - set cursor position.
input:
DH = row.
DL = column.
BH = page number (0..7).
example:
mov dh, 10
mov dl, 20
mov bh, 0
mov ah, 2
int 10h

INT 10h / AH = 03h - get cursor position and size.
input:
BH = page number.
return:
DH = row.
DL = column.
CH = cursor start line.
CL = cursor bottom line.

INT 10h / AH = 05h - select active video page.
input:
AL = new page number (0..7).

INT 10h / AH = 06h - scroll up window.
INT 10h / AH = 07h - scroll down window.
input:
AL = number of lines by which to scroll (00h = clear entire window).
BH = attribute used to write blank lines at bottom of window.
CH, CL = row, column of window's upper left corner.
DH, DL = row, column of window's lower right corner.

INT 10h / AH = 08h - read character and attribute at cursor position.
input:
BH = page number.
return:
AH = attribute.
AL = character.

INT 10h / AH = 09h - write character and attribute at cursor position.
input:
AL = character to display.
BH = page number.
BL = attribute.
CX = number of times to write character.

INT 10h / AH = 0Ah - write character only at cursor position.
input:
AL = character to display.
BH = page number.
CX = number of times to write character.

INT 10h / AH = 0Ch - change color for a single pixel.
input:
AL = pixel color
CX = column.
DX = row.
example:
mov al, 13h
mov ah, 0
int 10h ; set graphics video mode.
mov al, 1100b
mov cx, 10
mov dx, 20
mov ah, 0ch
int 10h ; set pixel.

INT 10h / AH = 0Dh - get color of a single pixel.
input:
CX = column.
DX = row.
output:
AL = pixel color

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.
example:
mov al, 'a'
mov ah, 0eh
int 10h
; note: on specific systems this
; function may not be supported in graphics mode.

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).
CX = number of characters in string (attributes are not counted).
DL,DH = column, row at which to start writing.
ES:BP points to string to be printed.
example:
mov al, 1
mov bh, 0
mov bl, 0011_1011b
mov cx, msg1end - offset msg1 ; calculate message size.
mov dl, 10
mov dh, 7
push cs
pop es

mov bp, offset msg1
mov ah, 13h
int 10h
jmp msg1end
msg1 db " hello, world! "
msg1end:

INT 10h / AX = 1003h - toggle intensity/blinking.
input:
BL = write mode:
0: enable intensive colors.
1: enable blinking (not supported by the emulator and windows command
prompt).
BH = 0 (to avoid problems on some adapters).
example:
mov ax, 1003h
mov bx, 0
int 10h

bit color table:
character attribute is 8 bit value, low 4 bits set fore color, high 4 bits set background color.
note: the emulator and windows command line prompt do not support background blinking,
however to make colors look the same in dos and in full screen mode it is required to turn off
the background blinking.
HEX BIN COLOR
0 0000 black
1 0001 blue
2 0010 green
3 0011 cyan
4 0100 red
5 0101 magenta
6 0110 brown
7 0111 light gray

E 1110 yellow
F 1111 white
note:
; use this code for compatibility with dos/cmd prompt full screen mode:
mov ax, 1003h
mov bx, 0 ; disable blinking.
