Peter, we do like what you propose. But Pavel would need your assistance
in order to implement the changes. We would also need the SW for the
chips replacing the FTDI chips. At least we need to be able to trust
that you will be able to provide it in good time when the new boards
will be back from manufacturing.

I know Pavel have tried to reache out to you about assistance re the
board updates. If we don't here back from you by next Wednesday, or if
you see that you can't assist with board updates and the SW we will take
the decision not to change the interfaces. We need to complete the board
changes and this is the last area.
