I assume you have a IIsi-
I have experienced the symptoms you describe.
I fixed it by :
1. turning on the serial port in /etc/ttys
modem port is tty00
printer port is tty01
2. turning off everything else.
console should be off
ttye0 should be off.
I also had trouble because I managed to cpin
/etc/ttys with all the \n characters changed
to \r (newlines->carriage returns)
Marc Parmet's port of Emacs did this automatically
and I didn't realize it.
If I boot single-user I have serial console checked
If I boot multi-user I have only serial-echo checked
hope that helps
