I have this thing that looks like a commlink card. Has 25 pins, it's an isa card. It says EPP/ECP TC020. There's also a whole bunch of jumpers on it. There's also a sticker that says, "TN018857." What's the difference between a commlink card and a printer card? thx
They're very similar, but they're not compatible. Plugging a parallel port into a commlink port could damage either or both of the ports. If the card you saw had a mention of ECP/EPP, then it's almost certainly a PC parallel port card and not a commlink card.
