[DUG] LPT ports

Does anyone know of a way to find all LPT ports installed on a PC and the
I/O address of the ports.

 

Up to now I've been using a 3rd party routine I found on the internet which
uses the registry to obtain this information, and this has worked well for
years, but a user has installed a USB based LPT port and it doesn't appear
in the usual place in the registry, although Windows sees it as LPT1.

 

I need the physical I/O address of the port as I need this to access the
individual pins on the port, using a 3rd party device driver service which
allows low level access to ports.

 

Thanks,

Ross.
