Thanks for fast and detailed answer. But I start to hate Intel...
Forum second time eat my huge answer...
You repeat that I already write as already maded...
Also I dont have option named like "RedirectionPort, etc" at MEBx, if you doubt in it I can make video with MEBx view. But I suppose that you just dont have AMT 5.0 version test stand to look at his MEBx.
Of course I use MC latest version 1.0.35. Firstly after un-provisioning its shows RedirectionPort as Disabled with gray-out big button "TakeControl", but after pressing small button in front of "RedirectionPort" option - it became Enabled and now its possible to press big button "TakeControl".
At Terminal at top left corner all the time I see only "TLS Secured, Serial-over-LAN - Disconnected" and error...
So problem apparently is about "RedirectionPort"... as I assumed...
But how to solve it?!?!
PS I just download all those madness quantity of software (in total I already have about 15 (!!!!!) programs for one AMT) and will try them... OMG...
