There is a workaround:

	tar cfB - file | rsh remotehost 'dd of=remote_tape bs=20b'	# write
	rsh remotehost 'dd if=remote_tape bs=20b' | tar xf - 		# read

Note:

	Although man files for tar may claim/imply that 20 blocks is the
	maximum block size for tar, vendors of Sun software routinely
	use 126 blocks for 1/4-inch tar cartridges, and I've seen 126
	blocks used successfully with 9-track mag tapes.
