The problem is that your serial setup doesn't provide DCD, but you're using a device that requires it to be available before completing the open(2). Think of DCD as indicating that a "connection is established" with the other side. The ttyd device is _supposed_ to block until a remote connection is established. If you can't provide a DCD signal, then just use "cuad" instead of "ttyd": The intention is that's for making outgoing calls you use cuad, so a getty waiting to open ttyd won't stop the open on cuad. In your case, it's probably ok for the getty to just hog the modem itself, so using /dev/cuad0 sounds like the right thing to do. I've no idea why it was working with ttyd before: it sounds like its working correctly now: maybe phk has fixed a bug in whatever was driving your serial hardware.
