Hello i have a dos program and a hand held device that i hook to the printer port that needs to read and write out on those ports but xp does not allow me to do this ,it works fine in windows 98. how do i address these ports to do this. is it a software issue and can i readdress them.
Thanks Jerald
 
Greetings --

WinXP, like WinNT and Win2K before it, will not allow software
applications to directly address hardware devices. This behavior is
by design and is one of the reasons the WinNT family of operating
systems is so much more stable than Win9x. For your handheld device
to work on these operating system, very specific device drivers must
be provided by the device's manufacturer.

If the device's manufacturer will not provide you with a patch,
new device driver, or product to render this legacy device
WinXP-compatible, you have little choice other than to replace it.
You'll need to acquire a version of your device that is designed
specifically for WinXP. Contact the manufacturer of the device to see
if any driver updates, patches, or upgrades are available.

Go to the below site, scroll down, and download the useport.zip
file. Userport will set the NT/2K/XP registry to allow usermode
programs to have access to the computer hardware like they had
with win 95/98. Set it to allow access to 378-37A, 278-27A, or
what ever is the address of your hardware parallel port (the
default settings will open the parallel port for access). Name
your desired memory address, run the program, and thats it. I
use it so I can run qbasic programs, assembly programs, and debug
programs to control the pins on the parallel port. Very nice
little application.
