This is a symptom of a receiver ignoring the availability of hardware flow
control, and allowing its TTY buffers to overflow. Since it is still reading
chunks of characters (just not fast enough), there appear to be many bursts
of dropped characters, causing major runs of CRC errors.

Look for options in stty like 'crtscts' and turn them on before you run rz
or sz.
