It will be troublesome to use standard windows com1 for this. Windows will try to use com1 as a default. You can make changes using windows "device manager". The anan is the source of the data and I use dxlab commander as the receiver of the data. Js8call can use dxlab as a cat device. The vspe connector will allow data to pass to any device that uses or can be set to com10. Usually com10 will appear once you enable it in the vspe program. I used com10 in vspe for no reason other than it is easy to remember.
