This sounds to me as though you turned the lines on in /etc/ttys but
something basic is wrong with the lines, most likely that their /dev
entries don't exist, possibly that you managed to mangle the "program
to run" field in /etc/ttys.

I would say, don't even try to turn them on in /etc/ttys until you can
get somewhere with

% sleep 999999 > /dev/ttyb &
% stty -f /dev/ttyb raw -echo 9600
% echo hello > /dev/ttyb
% cat /dev/ttyb
(type on the terminal and check that it gets printed out here)

(Of course, change /dev/ttyb to the correct name for the device, and
9600 to the baud rate you want to use.)

Once that works, _then_ try turning them on in /etc/ttys.  If it
_still_ doesn't work, there's likely to be a real problem; check
/etc/ttys to make sure the "getty" field is correct, in particular.
