I am trying to send cw with my laptop, always used LPT and W1WEF interface with my desktop. I have a USB to serial adapter that comes up as com 5, but CT for win only goes to com 4. Can the adapter be changed to 4 somehow? Can I get an adapter that comes up as com 1-4? It works with my regular logging program that can select com 5.. Thanks, Dick NY1E
