Serial Port Problems

[Dan D Niles]

More Dell 2950 woes.

I use serial ports to manage my FreeBSD machines remotely.  I've never
had any problems until now.  I've installed FreeBSD 6.2 on a Dell 2950.

The install goes without problems over the serial port.  After the
reboot, I get the typical:

FreeBSD/i386 (test.host.net) (ttyd0)

login:

and I can log in just fine.  If I disconnect and come back later
(sometimes), or if I hit return without entering a login name (always)
it starts spitting out junk like:

nooo~:Woo{;>6(|uww~now~nou})|t}}t9-

I can log in blind, but everything is scrambled.  Here is what I see
after logging in:

If I exit things go back to normal until I disconnect for a while or hit
return without a login name.

I tried loading an older FreeBSD to see if it was a hardware issue or a
FreeBSD issue, but my disks (mfi) aren't supported.

It seems like the speed of the tty is getting out of sync.

HELP! Any ideas?  

Thanks,

Dan
