For the record, that problem was on an HP Z-820 running Windows 8 Pro 64-bit.

WOW! That was a quick reply!!!! Thanks
I tried the com speed settings, but no go...
I took USB extender cable out (only thing left) and no go...
Installed Pronterface and it works like a charm! :)))))
Thanks again!

@shanegranger Just to give a little background, I think it was 1998 when I last used a TE... Ahhh, the good times!!

I've installed the USB driver and connected the DUET Ethernet I purchased from Fillastruder on 6/26/18.

I've installed YAT, and configured YAT for the Com port.

I've Changed the End Of Line settings to "<LF>"

YAT shows Open and Connected but when I send "M115" I get "Receiving" but nothing happens in the window.

Any ideas??? Why was I thinking I could get through the first terminal command in the first 24hrs???? Lol! Any direction is appreciated.
