Could you please, give an example on hot to use mouse (handle clicks) under dos/win-dos-box?
Thanks! |

look for description of interrupt 31h services (i think, if not 31h then some similar number).

Mouse functions are in 33h interrupt.

Ok, I That it is int 33h but how to use it?

To calculate from mickeys to pixels, first use 001bh function to get mickeys per pixel values for x and y axis. Then use function 000bh to get the shift of the mouse in mickeys. To get it in pixels just divide the values obtained using 000bh function by those obtained using 001bh function.
To get the new position of mouse cursor use 0003h function. But watch out, as this function returns x value in range 0-639. |

from asmcompo.org
i have included a smaller vewrsion note that mouse coordinates can be larger than 319=xmax.

Wow, thats *my* demo, someone just posted me a link to this forum, very bizzare
Code: mov ax,03h ;get mouse status int 33h cx = X co-ordinate dx = y co-ordinate |

Ralf Browns Port info, "GET MOUSE PACKET"
associated with IN AL,60h (get key press from port) Has quick mouse stuff ? There is a Port check to see if a mouse packet is ready. One could make a macro to check for mouse movement/click and scatter it about in the main program loop ? I don't have specfic's available, only the above hints, sorry. |

I had a squeeky berring in my mouse & the tech on the phone said to:
look on the other end, lift the tail, squirt oil in the little hole, but be care full not to get bit in the process. So I looked for the hole under the cord, and realized that the asshole was on the phone. |

A program for xp console text mode, needs mouse initialization stuff?
I want to take the coords and i see that this simply works.. Code: mov ax,3 ; get mouse position cx = x, dx = y int 33h ; mouse buttons: left bx = 1, right bx = 2, both bx = 3 shr cx,3 ; divide by 8 for 80x25 screen shr dx,3 |

defines screen region for updating in which the mouse is hidden if found these coordinates (INT 33,1 must be used to turn cursor on again) - see ~INT 33,1~ :int 33,13 ^INT 33,13 - Set Mouse Double Speed Threshold AX = 13h DX = threshold speed (mickeys per second, default 64) returns nothing -

used before mouse functions 16h and 17h to determine memory needed to save mouse state before giving up control of mouse to another program :int 33,16 ^INT 33,16 - Save Mouse Driver State AX = 16h ES:DX = far pointer to mouse state save buffer returns nothing - used to save mouse information before relinquishing control to another programs mouse handler - see ~INT 33,15~ ~INT 33,17~ :int 33,17 ^INT 33,17 - Restore Mouse Driver State AX = 17h ES:DX = far pointer to mouse state save buffer returns nothing - used to restore mouse information after regaining control from another programs mouse handler - see ~INT 33,15~ ~INT 33,16~ :int 33,18 ^INT 33,18 - Set alternate subroutine call mask and address AX = 18h DX = offset to function CX = user interrupt mask: ³F-8³7³6³5³4³3³2³1³0³ user interrupt mask in CX ³ ³ ³ ³ ³ ³ ³ ³ ÀÄÄÄ alt key pressed during event ³ ³ ³ ³ ³ ³ ³ ÀÄÄÄÄ ctrl key pressed during event ³ ³ ³ ³ ³ ³ ÀÄÄÄÄÄ shift key pressed during event ³ ³ ³ ³ ³ ÀÄÄÄÄÄÄ right button up event ³ ³ ³ ³ ÀÄÄÄÄÄÄÄ right button down event ³ ³ ³ ÀÄÄÄÄÄÄÄÄ left button up event ³ ³ ÀÄÄÄÄÄÄÄÄÄ left button down event ³ ÀÄÄÄÄÄÄÄÄÄÄ cursor moved ÀÄÄÄÄÄÄÄÄÄÄÄÄ unused - entire mask is set to zero when ~INT 33,0~ is called - up to three handlers may be defined with this call - mask should be cleared before program exit - when handler is called it receives parameters in the following registers: AX = condition mask causing call CX = horizontal cursor position DX = vertical cursor position DI = horizontal counts SI = vertical counts DS = mouse driver data segment BX = button state: ³F-2³1³0³ ³ ³ ÀÄÄÄ left button (1 = pressed) ³ ÀÄÄÄÄ right button (1 = pressed) ÀÄÄÄÄÄÄ unused :int 33,19 ^INT 33,19 -

returns vector to function defined by ~INT 33,18~ - searches the event handlers defined by INT 33,18 for a routine with a call mask matching CX :int 33,1a ^INT 33,1A - Set Mouse Sensitivity AX = 1A BX = horizontal coordinates per pixel (ó 100) CX = vertical coordinates per pixel (ó 100) DX = double speed threshold returns nothing - sets mouse sensitivity by setting the ratio of the mouse coordinates per screen pixel - provides same results as calls to both ~INT 33,F~ and ~INT 33,13~ - these values are not reset by ~INT 33,0~ :int 33,1b ^INT 33,1B - Get Mouse Sensitivity AX = 1B on return: BX = horizontal coordinates per pixel (ó 100) CX = vertical coordinates per pixel (ó 100) DX = double speed threshold - returns mouse sensitivity information as the number of mouse coordinates per screen pixel :int 33,1c ^INT 33,1C - Set Mouse Interrupt Rate (InPort only) AX = 1C BX = rate code = 0 no interrupts = 1 30 interrupts per second = 2 50 interrupts per second = 3 100 interrupts per second = 4 200 interrupts per second - work with the InPort mouse only - sets the rate the mouse status is polled by the mouse driver - faster rates provide better resolution but take away CPU time - values in BX > 4 can cause unpredicatable results :int 33,1d ^INT 33,1D - Set Mouse CRT Page AX = 1D BX = CRT page number returns nothing - sets the CRT page which the mouse cursor is displayed - see ~VIDEO PAGES~ :int 33,1e ^INT 33,1E - Get Mouse CRT Page AX = 1E on return: BX = CRT page number cursor is displayed on - see ~VIDEO PAGES~ :int 33,1f ^INT 33,1F - Disable Mouse Driver AX = 1F on return: AX = 001F if successful FFFF if error ES:BX = previous ~INT 33~ vector - restores vectors for ~INT 10~ and INT 71 (8088/86) or INT 74 (286+) - ~INT 33~ interrupt vector (software) is not affected - use of the vector returned in ES:BX to restore the previous INT 33 vector can cause problems since it contains the value of INT 33 before the driver was installed; any other hooks into INT 33 set after driver installation will not receive service :int 33,20 ^INT 33,20 - Enable Mouse Driver AX = 20h returns nothing - reinstalls the mouse drivers interrupt vectors for INT 10 and INT 71 (8088/86) and INT 74 (286/386) - see ~INT 33,1F~ :int 33,21 ^INT 33,21 - Reset Mouse Software AX = 21h on return: AX = 0021 mouse driver not installed FFFF mouse driver installed BX = 2 mouse driver installed - similar to ~INT 33,0~ but does not reset the mouse hardware or display variables - both AX and BX must be correct for successful reset - interrupt routines set through ~INT 33,18~ are preserved - resets the mouse to the following defaults: . mouse is positioned to screen center . mouse cursor is reset and hidden . no interrupts are enabled (mask = 0) . double speed threshold set to 64 mickeys per second . horizontal mickey to pixel ratio (8 to 8) . vertical mickey to pixel ratio (16 to 8) . max width and height are set to maximum for video mode :int 33,22 ^INT 33,22 - Set Language for Messages AX = 22h BX = language number (with /L switch value): = 0 English n/a = 1 French F = 2 Dutch NL = 3 German D = 4 Swedish S = 5 Finnish SF = 6 Spanish E = 7 Portuguese P = 8 Italian I returns nothing - only works with international version of the mouse driver - see ~INT 33,23~ :int 33,23 ^INT 33,23 - Get Language Number AX = 23h on return: BX = language number (with /L switch value): = 0 English n/a = 1 French F = 2 Dutch NL = 3 German D = 4 Swedish S = 5 Finnish SF = 6 Spanish E = 7 Portuguese P = 8 Italian I - only works with international version of the mouse driver - returns English (0) if not international version - see ~INT 33,22~ :int 33,24 ^INT 33,24 - Get Driver Version, Mouse Type & IRQ Number AX = 24h on return: BH = major version (see below) BL = minor version (see below) CH = mouse type: = 1 bus mouse = 2 serial mouse = 3 InPort mouse = 4 PS/2 mouse = 5 Hewlett Packard mouse CL = IRQ number: = 0 PS/2 = 2 ~IRQ~ 2 = 5 IRQ 5 = 7 IRQ 7 - version 6.1 would be represented as BH = 06h, BL = 10h how to use software int is not to explain to an asm coder. just set different registers to desired values, int 33h, returns the right values. important note: int 33h doesn't work very well under winXP particularilly functions 2, 7 & 8, set mouse position, set X resolution, set Y resolution. oh gosh!!! |
