[Elecraft] No Connectivity to my COM Port

[Carter Craigie]

For some reason I can no longer connect my KX3 to my computer. I have tried
rebooting. changing the connection cable from my computer to the back of my
KXPA100 amp, and so forth.

Usually I have been using COM3, but I get a message that that com port is
in use by another device. Hmmm... It was working yesterday...

Any help from anybody, please? I'm stumped.

My phone number is (540) 250-8184.
My email address is carterwc128 at gmail.com

I hope someone will help me.
