BZW, you may have noticed that the protocol between ORC and PCLink0
has also been slightly modified (ORC now sends ACK after sending either
SND or REC, and in addition sends REQ after sending or receiving packets).
This effectively creates a "confirmation bracket" around the packages. Better.

Best, Andreas
