Low level access to parallel ports under win2k

Incubus · 04-22-2002, 10:19 PM

Does anyone know how to do raw reads and writes to a parallel port under windows 2k without having to write a driver from scratch?
Alternately does anyone know how to locate a parallel port within the port memory space. For instance lpt1 usually defaults to 0x378 - how can I find out where windows thinks it is?

As far as I know Win2K does not allow any access to these ports in user mode......
