Okay, thanks for the lead. I finally got the connection problem solved. I purchased a USB to RS232, USB Serial Adapter with FTDI Chipset,USB 2.0 to Male DB9 Serial Cable for Windows 11,10, 8, 7, Vista, XP, 2000, Linux and Mac OS(6ft) off of Amazon for $12.99. Then I went to
https://ftdichip.com/drivers/ and loaded their most recent Windows driver package and installed on my new Windows 11 laptop.
Went out to the hangar and voila! It connected to my FlightDek D180 just fine.
Thanks for the tip.
