Identical to ours... Well, the reason you'd get boot messages and kernel output would be that neither of those (AFIAK) bothers to check for things like DTR/DSR and DCD. getty, on the other hand, does. That's what makes me think it might be a cabling or adapter issue. The 3wire.9600 test, I assume, should've worked though... > It's really really strange that I can see the whole boot process but don't > have a login prompt in the end. strange. Has this box been "upgraded" from RELENG_6 or anything like that? I remember encountering a situation with one of our RELENG_6 boxes where serial console would work fine up until the point of getting a login prompt via getty, which never worked. Rebuilding kernel + world fixed the problem (time delta between kernel/world builds was over 100 days, and during that time I'm sure there were serial console changes). -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
