The case in question (the 24+ hour phone call) was on a 202C
modem and nothing to do with uucico or anything similar.  I've
gotten direct mail from the person with the modem confirming that
the application was specialized and half-duplex.

Secondly, no changes to any software are going to help get you out
of many modem self-test lockup situations, since DTR is frequently
IGNORED by the modems in such instances.  This is a situation
where the hardware must take the responsibility, not the software.
All software can do is try drop DTR to try hangup, but if the modem 
ignores that and keeps the call up the charges are going to continue.

Moral: Don't buy modems that force you to keep remote-test enabled!
