AT&D0 doesn't use DTR at all, so that can not be a setting expected to hang up the modem. There are only 3 ways to disconnect once a connection is established:
1) Use AT&D2 and toggle the DTR line.
2) Use +++ to enter command mode, and then ATH to terminate the connection.
3) The remote side terminates connection.
This is the only way a real (or emulated) modem can disconnect.
The default value for *D should be 1 (inverted) for the WiModem232. I will change that in the documentation. If your programs looks for the DCD signal, then &C should be 1.
You would need a NULL modem cable connected to a 'Y' cable. The NULL modem end would plug into any PC.
