dd | remsh dd under AIX 1.2

[J.E.Ward]

I have tried several times and ways today to do something I've done on
lots of other machines with no problem, essentially:

dd bs=1024k if=/dev/rmt0 | remsh HostWithTapeDrive dd bs=1024k of=/dev/rmt0

This aborts in the following manner under AIX 1.2:

AIX instfe 1.2> dd bs=1024k if=/dev/rmt0 | remsh rt dd bs=1024k of=/dev/rmt0
dd write error: Invalid argument

3+0 records in
2+0 records out

Can anyone tell me why this doesn't work?  As I said before, I've done
this sort of thing in the past on other systems with no problem.
Thanks in advance...
