Ok, reading the Stollmann TIO doc carefully, it is clear that we do not
correctly follow the mandatory initialization
of the connection to the Terminal IO. So my guess at this point is, that
that is the main reason things do not work. I am
working on an improved implementation of the TIO handling, and taking
care not to break other BLE stuff. Hopefully
later today an update on this.
