sounds like the TAC is in 7-bit ASCII mode, rather than binary.  Have
you tried B I S and B O S (I think those are the commands)?  They should
cause the TAC to go into binary mode with eight-bit characters (the
complemented count in the header is 8-bits, even if everything else is
only 7 bits).

    Good luck
