Sounds like the modem is not dropping Carrier Detect to the serial port or the
computer is not detecting it and releasing the connection. You might have the wrong
type of serial cable, one that has Carrier Detect wired ON at the computer end, it
the computer is not reporting loss of Carrier, just the modem itself. These are usually
sold for use on Apple Computers and sometimes come packaged with external modems
sold for use only on Apple computers.
You should be able to power cycle the modem and Windows should release the connection.
If it does not, you may need to try a different serial cable as a test to make sure
you don't have the wrong type. (Borrow one, don't buy one just to test it.)
I have seen the same type of connection loss where the "connection" is still in
use, and power cycling the modem does not free it up.
There is no process that you can kill to clear this type of connection hang. I
would see them a lot when the ISP was having problems at their end with line noise
causing their modems to drop lines. You wind up having to reboot the system so you
can dial again.
This process is controlled through DLL's and there is no doubt a RUNDLL32 function
call to some DLL which will release or reset the connection and allow you to dial
again. (I remember reading about one a long time ago.) You might be able to find
someone in one of the dial-up Communications forum web sites that might know how
to do this. That would be something that could be setup as a shortcut and would force
the release of the connection.
