I have been following this question and seem to be having similar problems with dialin modems. The modems in question are either Netcomm E7F or Banksia MX series. I set the modems to follow carrier and respond to DTR (at&c1&d2), but the getty seems to exec login well before the modem answers. Subsequently, even if the modem answers we never actually respawn the getty.
