I'm just got a new Windows 7 64 bit and they don't make the old style modems for it. So i got a 56k Zoom modem that comes in the USB port. It shows up on my divises as COM3. When i run the program with DosBox it seems to run but when i try to configure it to call out on COM3 it yields the following error: FFF2 com port not found.

How can i fix this?
