I'm working on that among other things.
The problem was (and still is) that commands from PC-Software to the Radio works OK, but the other direction does not work.
This means that you can send commands to the radio but the software (TRX-manager or/and PCC-xxxx) does not show changes on the radio side.
So you are not forgotten although not helped (yet) either.
Sorry for that. Hopefully I will find what the problem is
