• Yes, I was able to simply quit the keyboard assistant without any bad consequences (what I did not know when it first appeared)

    And, yes, Apple never handled BT properly in the past - I always had problems. Working with a "black box" and just guessing why it does not work is quite difficult - and Apple wasn't of any help here.

    That said, the serial console you mentioned would have been helpful - although I wanted to avoid having to solder on the Puck device...in fact, I once hoped to complete that "little" project within an hour (oh God, I was so naive!)

    Nevertheless, in the end I succeeded!

    Thus: thanks a lot for that wonderful device called "Puck"!
