I checked the logs and it looks like the bus freeze at mode 08 bombardment and than resumes normal communication.

Can you try to give a 4-5 attempts burst than wait for silence, than again 5 attempts,than wait for silence. I think when the mode 8 went through at least 5 second silence can be observed.
What is the normal silence on end of message , can we use that to identify the end of messages, For example read byte to byte delay and when a pause longer than the expected 8192 baud is received the end of message can be flagged and the buffer dumped.
