Hello, fellow Geeks. This is my first post! This looks like a great Forum, and I look forward to poking my nose in now and then. 
Now, to my question...
I have some older, but still useful 16-bit relay cards. 3 of them are ISA, and one is PCI. They feature 16 relays controlled by the computer, and they have 16 digital inputs. The ISA cards use DIP switches to set their base addresses, and the PCI is PNP.
The model numbers are:
PCI-PDISO16 (PCI)
CIO-PDISO16 (ISA)
I was wondering if anyone has more info or has written any code that can be used to access these cards... I'm familiar with GWBASIC (yes, I'm a fossil) 
but have just started to delve into working with AutoIt scripting language. It appears that "Peek" and "Poke" don't access either the PCI or ISA. (I tried different DEF SEG and also INP and OUT. That was all no good, so GWBASIC is out.)
I just need some means to read the status signals (two bytes) and turn the relays on or off (also two bytes). Naturally, some kind of simple interface to turn the individual bits into "buttons" and "lights" on the screen would be a plus. Does anyone have some ideas or code snippets I could look at that could get me going in the right direction?
Thanks!
Willie...
