[ASM] OUT on XP


Hello,

I have an old ms-dos software running on DOS and XP, but on XP the serial
com don't work...

I have a piece of code who i think can't run on XP (sorry for my bad
english) :

<code>
vide_port proc far
PUSH BP
PUSH DS
push ax
push dx

mov dx,ad_pcom
IN AL,DX
IN AL,DX

pop dx
pop ax
POP DS
POP BP
RET
vide_port endp
</code>

what do you think about it ? how can I modify it (i don't know very well
asm)...

thank you for suggestion
