To find the address of your parallel port card in a terminal window
lspci -vYou will see something similar to this
0000:00:10.0 Communication controller: NetMos Technology PCI 1 port parallel adapter (rev 01) Subsystem: LSI Logic / Symbios Logic: Unknown device 0010 Flags: medium devsel, IRQ 11 I/O ports at a800 [size=8] I/O ports at ac00 [size=8] I/O ports at b000 [size=8] I/O ports at b400 [size=8] I/O ports at b800 [size=8] I/O ports at bc00 [size=16]
In my case the address was the first one so I changed my .hal file from
loadrt hal_parport cfg=0x378to
loadrt hal_parport cfg="0x378 0xa800 in"
note the double quotes surrounding the addresses.
addf parport.1.read base-thread addf parport.1.write base-thread
so the parport will get read and written to.
You need to supply the interface board with 5 vdc. I just hacked a plug from a busted fan and plugged into a large plug from the power supply of the computer the black and red wires. Electricity don't know what color wires are so use your meter to verify you have the voltage you need.
