1. Control Panel
2. System
3. Hardware
4. Device Manager
5. Ports (COM & LPT)
And from there you can renumber your port.
Why, in this age of USB ports, would one want to know how to change a COM port number?
I have a pc, not a mac, because of my embroidery software. It only runs on a pc … or it only ran on a pc when I was buying my laptop; that was several years ago.
This software, which has been updated since the age of USB ports started, uses a COM port, AND it will only use COM ports 1-4. When I add the USB-to-COM adapter to my system, I usually get COM port 8 added.
This question comes up every so often on the mailing list, so I decided to document my response so I can look it up next time.
Maybe I’ll start a FAQ.
