I'm setting up Mach to replace an old dos based system. The PC did not have a db25 port so I added a card and driver which it shows as LPT#3 with first address line of 9c00-9c07. The driver test in Mach was successful. Under Ports and Pins though I only have LPT1 or 2 availale and neither will accept the address 9c00 or 9c00-dc07. Under the Function CFGS/Serial Monitor i get a message "Port not enabled - enable in ports and pins and restart."

What am I missing?
