TTL-Problems with PCI-parallel port card

[Trevor Newell]

Hm. It's peculiar that the motherboard worked when it had a parallel port built-in, but the PCI-parallel port card didn't work.

I wonder if it's the card itself that was malfunctioning?
Thanks for the update on the situation.

FYI, running a forum search on "ttl parallel" will turn up a healthy portion of discussion on this. I can mention here though that one unresolved issue remains that port addresses greater than 32768 (decimal, or 8000 hex) may not work. On-board parallel port addresses (e.g., as opposed to OS-assigned add-on card addresses) tend to stay much lower than these max values and so that is usually a fix if this is the issue. But then again, if you had an on-board parallel port (i.e., directly built into your system/mother board) you probably wouldn't be reading this. Sigh. In any case, for v2010, we should have it worked out such that all port addresses work fine--to infinity and beyond.

@newell:
I connected an old HP Laserjet and printed with it. So I concluded that the card works.

@Blair:
Ah, ok. The decimalcodes of my card are about 60000, so it seems that it could not work ;-).
And that was exactly my question. We wanted to build up new labmachines for the EEG anyway, but I was unsure if I just made a mistake while testing the stuff with existing machines. So no worries, we didn't exchange a mainboard in an existing machine to get the stuff run ;-)
But I must confess that I, apparently, have calculated wrong decimal-values for the hex-values of the I/O-area of my card (SHAME on me).

Anyway, thanks to both of you for your responses,
best,
Tom
