For some reason (possibly related to the fact that the Penril is a smart modem, and keeps DCD up all the time, so open() succeeds even when no call is incoming), specifiying incoming makes the getty constantly "pick up" the phone. If you specify bidirectional instead, uugetty is run on the line. Uugetty not only knows how to step out of the way of outgoing calls, but is a little bit smarter about smart modems. -- -Paul S. R.
