Will this work on Windows 2000

[Ryan Groom]

I made a little DLL thanks to code on this forum in PB. It talks to a custom ISA card we made.

Will this code work? IF not how can I do it in NT/2000?

Thanks,

Ryan

$COMPILE DLL

DECLARE SUB pbOut(BYVAL PORT AS INTEGER, BYVAL value AS INTEGER)
DECLARE FUNCTION pbInp(BYVAL PORT AS INTEGER) AS INTEGER
GLOBAL i AS INTEGER

SUB pbOut(BYVAL PORT AS INTEGER, BYVAL value AS INTEGER)
! mov AX, value
! mov DX, port
! out DX, AL
END SUB

FUNCTION pbInp(BYVAL PORT AS INTEGER) AS INTEGER
! mov DX, port
! in AL, DX
! mov FUNCTION[0], AL
END FUNCTION

It won't work... apps cannot directly access hardware at Ring-3 (application) level.

The only way is to install and use a Kernal-mode driver (these are the NT equivalent of a Win9x VxD).

Wander over to www.lvr.com for information on NT-based drivers for this sort of purpose.

Hi, You can use that code under NT/Win 2000....There's an
undocumented API called the I/O premmissions map that allows you
to set a what port addresses can be 'unprotected' by windows
I need to dig up the details and I'll get back to you.
