I've been getting at most ~60 KBps. My only reservation in removing this would be, it came in handy and still primarily works. It's useful absent any other link but imposes a large overhead. Should this driver still use splhigh()? I'll also note that even NetBSD seems to omit plip support at the moment. So I'll take that as a prophetic nod from the code-reaper. Funny thing is now I'm having trouble reproducing the IP header problem.. could it be cable/hardware that was the culprit? > Scott Thanks.. Allan
