Sadly no...  Unless the retransmit is a different packet, but if it
keeps retrying the same packet that was dropped, it will never send
the packet...  The dropping seems to be data related...

Good luck...  I didn't have any when trying to deal w/ them...

You might have better luck talking w/ Glomation...  It shouldn't be
hard to bring it up on a different board...  Already have the serial
port driver working for the EP9302...
