Have you checked to see that the other site's modem is set to hang up when
the DTR line is dropped?  Also make sure that they have the modem port
configured HUPCL so that DTR is dropped when the last process closes on that
tty line.  I suspect the problem is one of the above.
On a Hayes 1200 smartmodem, switch 1 determines how DTR is treated
(it should be up).  Other modems probably have similar switches.  A simple test
is to call the other site (via cu), log on and then log off.  If the switches
are set right the phone should hang up.  If it doesn't, it is a problem at
their end.
