I have N4PY Pegasus Plus running on a Mac using crossover except that the program can't connect to the USB external interface (US Navigator). How do I assign the correct COM port to the N4PY program so it can communicate with the radio?
There is a post on the Codeweavers website which explains exactly how the procedure should be done for the COM port be recognized on Crossover. I recommend you access the page and then follow the instructions posted on that page.
