118. MT: revised error handling failed to set tape mark status on space file forward/reverse.
119. IO: UEND flag in the wrong bit position in status word.
120. DP: SEEK(I), RECAL(I) must be coded as fast operations.
121. COC: Transmit long space is 0x6, and stop transmit is 0xE.
122. COC: Received break generates a data-in channel transaction with a flag bit set
in the line number.
123. DP: dp_inv_adr error must set a TDV visible flag (i.e., PGE) before UEND.
