OK, I've scan COM ports again in Test mode with GNS TMC.exe, and I found TMC signal at COM port 4
When I run GNS TMC.exe (not in Test mode) but in normal mode from avic menu- access to this port is restricted !
I am trying do run TMC in iGo Primo, but in the same time I have running standard iGo (btw. in iGo I also don't have any TMC, only scanning frequencies)
so
How to release COM port 4, THAT IGO Primo has access to it
