Problem reading foreign TAR tapes

[FIDLER::LEVINE]

	I am vax cluster system manager with a user who just got a 
Silicon Graphics IRIS 4D/240GTX running  IRIX (AT&T System V with 
BSD Extentions) V3.1 . He wants to be able to exchange data between his 
computer and my cluster useing mag-tapes. I used the TARWRITE program
supplied in the Spring 89 VAX/L&T SIG Tape VAX000.TOOLS directory to
build a tar tape, but he is unable to read it even useing the command

 dd | tar . . .

is there anything else to try on the VAX or Silicon Graphics to be able
to produce a readable tar tape, or is there a way on the Silicon Graphics
to read/write blocked tapes?

	Please respond directly as I do not get the INFO-IRIS conference.
