Robert,
I have a FreeBSD based router running on an Intel PIII board (D815EFV) that=
=20
uses a serial console. I redirect to com1/cuaa0 at 115 kbps. I also=20
configured FreeBSD to use a serial console as the primary console, and I=20
haven't had any problems with the router failing to boot, either with or=20
without a terminal attached. Finally, I set up a getty session, so I can=20
login via cuaa0. The only messages I miss are the fdisk/startup messages.
Sorry I can't help, but I would suspect a configuration issue.
