My guess is that you are relying on the remote system to hang up the phone
when you log out.   Your computer ought to be hanging the phone up itself.
When you close the line on your side, your terminal driver
should be turning of Data Terminal Ready.  If your Data Terminal Ready
line is wired through to the modem,
then your modem will hang up.  On the other hand, if you have DTR
permanently wired high, then the problem you report will occur.
