Then I was hallucinating that memory, because that's nothing like the comparatively plush serial accomodations in Apple's hardware. > I had the same problems with Solaris btw.

By "newer sparcs" I presume you mean sun4u machines? (The stuff above is all sun4c... there are some "newer" sun4cs than the IPC and IPX, I think, but I'm not sure.) Ever played with serial on the sun4m machines? (NOT sparcs, but m68ks.) I'm inclined to think that's where the hallucination came from, but I'm not sure. -- gabriel rosenkoetter gr@eclipsed.net Attachment:
