There are a number of open PR's (i386/5698, kern/6099) covering LPIP problems. I don't recall seeing any reply either. >I'm about to look at ECP+DMA with a basic master/slave protocol.

I have done a bit of thinking about how to go about handling contention, but didn't come to any firm conclusions. I only have one ECP machine, so I can't use an ECP protocol in any case. My only comment is that it would be useful if the protocol could also be used on a normal bi-directional parallel port.
