When you start up SoftWindows there is a pull down menu titled "SETUP". Under this menu you can elect to either use, or not use the communications port. The work around is to turn the communications port off.
When Insignia wrote SoftWindows they set out to deliver a DOS emulator, and DOS emulation does include port arbitration, so they didn't develop code in their emulator to share ports with a Macintosh computer. It's an inconvenience, but they feel by allowing the user to manually turn the communications port on and off is the best they could do.
