2. Finding ComPort software
There are lots of different software for finding comports, but the issue is you may not have it on the computer after a disaster.
Windows app Device Manager will allow you to see what comport’s you have.
There is a big advantage of using native applications in Windows 7-10 like these…
Control Panel, Device Manager, Notepad, Wordpad, Paint, etc.

3. Finding your COM Port Open Device Manager
Open the “Ports (COM & LPT)” tab
Plug in your TNC’s USB/or USB to Serial adapter
The COM Port that is added is the one for your TNC.
Make note of the it (COM?)
If you are using a serial cable DB9 to DB25 it most likely will be Com 1 or 2
