If you go into the Windows Device Manager, and click on the '+' sign
next to "Ports (COM & LPT)" you will see the port assignments.  You
may be able to right-click on one of your virtual ports (like COM7)
and assign it to a different number.  But if the radio works OK on
COM7, why not leave it that way?  Remember, you can only have ONE port
assigned to a given number.

I don't have any advice to determine what application is trying to
access COM3 besides DX4WIN.  Go through all the DX4WIN preference
tabs, and make sure that all devices are using a unique COM port #.

If you had created virtual COM ports because you are using a
USB-to-serial cable (or a RigBlaster, microHAM, etc. device), try
deleting all the virtual COM ports, then reboot, then create only the
ones you need.
