But, as we've discussed, BXXP will not mandate a retransmission
queue. Therefore, I would consider retransmission beyond what's
reasonable to implement. In my current thinking, I'd probably just
close the connection, because I'm not even sure that a retransmission
would satisfy BXXP's frame consistency checks.
