Try turning clocal off on the host and port you are running kermit on.  Even
then, I still have yet to get getty to work at all, it's always stuck in
'siodcd'.  I've noticed via debugging output that the DCD change bit does raise
for a read, but that teh DCD status bit stays at zero the entire time.  The
sio driver seems to ignore the change bit and only read the status bit, so it
thinks DCD is never raised and hangs forever on open.  Note that I can get a
getty fine on a serial console, just not on a /dev/ttydX that's not also the
serial console. :(  I've had this problem since before PRE_SMPNG however.
