Delay problem

[Lionel Pinkhard <lionelp@worldonline.co.za>]

Hey guys/gals,

I'm having a little problem with some Macro Assembly coding, I'm trying to
write a hardware detection routine, but for that I will need to create an
80 microsecond delay between two test routines, how would I do this in
Assembly? Basically, this would be the same as 'usleep(80)' in C/C++, but
I have never tried this in Assembly, sorry. My detection routine involves
a timer, so this will have to be accurate. Otherwise, I would have been
able to do this myself :-).

My code goes something like this:

code segment byte public

assume cs:code, ds:code, es:code

	org	100h

_detect:

	; first test code

	; here I want the 80ms delay

	; second test code

	; check hardware and return output

	mov	ax, 4c00h
	int	21h

stat1	db	? ; first test results
stat2	db	? ; second test results
; messages for output

code ends

end _detect

Well, I hope this is enough detail, I wouldn't want to elaborate too much,
and waste bandwith! Basically, I just need the Asm equivalent of the
'usleep()' function.

I really hope somebody can help me out!

Ciao,

Lionel
