I have a parallel port PCIE card on my MP. I'm using Parallels 7 to run windows so that I can use a program called Mach3. Anyway, my problem is that I need to identify the port address of the PCIE card in Mach3 so that I can communicate with some hardware. Right now under ports in device manager it shows: Resource type Setting I/O Range 4000-4007 I/O Range 4008-4008 What would I enter for a port address? The default in Mach3 shows up as 0x378 or 0x278.
