[Elecraft] K3 Mini Term Mode

[dgb]

I am remoteing with the Remote Rig twins, K3 Mini to my K3 at home.

Has been working good till all of a sudden. What happens is when I turn 
on the Mini, it goes into the Term mode as normal and I can hear stuff 
from the K3 at home BUT the Mini won't control the K3. The display is 
stuck on it's boot-up screen and the knobs does nothing, no control. I 
think the K3 hasn't shut off at home nor can I shut it off with no 
control from here. I have it hooked to a PC at home and a laptop here. 
Connecting with Teamviewer works well.

What should I look for?
