If you look in device manager in windows and find which comport the rs232 converter is using then in dreamup (after restarting dreamup) select the correct comport things should work then. If you dont see your rs232 converter in Ports (device manger in windows) it may mean you have no driver loaded for your converter in windows.

The other problem why you may be getting that message is that your comport is already assigned to another program. Close that program and restart dreamup with the correct comport selected.

Hope that helps!!!
