                      Yet when I run SZ, I get many CRC errors/retransmits.

You can try using a smaller frame size, i.e.


sz -l 768 file.dat
sz -l 512 file.dat
sz -l 256 file.dat

You might just be overflowing what your hardware/software combo can handle.

I have to use 768 here.  Maybe we need to take a look at the FAS serial
driver and what we need to do to make it fly under FreeBSD.

Good Luck,
