If you drill down under the Advanced button in the Serial Port Control panel
area you can reset the Windows COM port for a single port.
If you know the port is not in use, ignore the message that tells you that
it is in use, when you change the port number.

You can also search the Windows registry for the "COM Port
Arbitrator". It is a 256 binary bit map of the assigned, and the
next to be assigned, COM port.  That is where you reset the ever
incrementing COM port number.


If you are using a USB converter and want it to stay put, do the
following.

This should work for non-FTDI devices, that have serial numbers, just match
the VID/PID.
