Giving the command line options you are using might help, but I suspect that
this is due to some incompatible changes in the rmt protocol that were made
in 3.2. Unfortunately, this wasn't caught as a problem until it was too
late too fix it. In 3.3, we still use the new features added in 3.2, but
we fall back to the 'standard' rmt protocol if we don't see an indication
that the remote understands the new protocol.
So, about all you can do until you upgrade is to fall back on something like:
bru -cvfb 32 - files | rsh host dd bs=32 of=/dev/rmt0
(I'm a bit hazy on this, since it has been a while, so I may have erred on
the finer points.)

Life would be so much easier if we could just look at the source code.
