It looks like you've already got a solution to this problem, and this
won't be very useful if the 40kHz figure is right, but I figured I
might mention it anyway. Have you thought about using the feature of
the callin device of the "open" call blocking until it gets CD? You
should then get a SIGHUP when CD drops.
