1. Windows 10 keeps track of every device that was ever connected, and just keeps incrementing
??? the COM# port ids.? Some 'older applications' like TeraTerm may only 'acknowledge' ports 1 - 9 or so.
??? In Device Manager, you can show hidden and clean out devices that are not in use, but are taking up
??? lower COM# numbers.
2. The TT4 provides feedback on initial boot up. You need to see this initial message in TeraTerm
??? This can be difficult with the TT USB cable as it powers the TT4 on J2 pin 4.
??? Three options here:
??? a) Open case and use the jumper for the TT4 pin 4 selection to cycle and reset the TT4
??? b) Make sure the TT4 is not powered through the "Rado port' (J1 pin 7) and cycle power using J2
??????? You cannot disconnect / reconnect the USB side because the TT4 is initiated
??????? before the PC sets up new COM# port and makes it active.
??? c) NOTE: carefully ground the Atmega chip reset pin - doesn't take much, just a touch to ground
??????? Kit version - Micro Pin 9 to ground Micro pin 11.
??????? PreBuilt version - micro pin 4, but no easy access.?
????????????? Schem references access on J5, but I don't see that connection on the board.
NOTE about 2b:? Be very careful of the JP6.?
???? JP6 must be on Vcc - Make sure it is NOT Vin when connecting the TT USB cable.

Good to know it works for others. Not sure why it didn't work the first time around. I made sure I had installed the drivers from the Byonics website. Perhaps newer drivers already existed? I dunno. Anyways, I uninstalled all the drivers, reinstalled the drivers from Byonics, rebooted, and it is recognizes it now.
At this point, I can't get TeraTerm to connect to it. It shows conncected in the COM port, but nothing displays in the terminal window. The only thing different from the quick start that I can figure is that I'm not connected to a radio right now. I was just figuring I could configure it first. Cycling the device by un-plugging and plugging it back in has resulted in several BSODs so far.
