This message is sent from a target to an initiator to indicate that the execution of a
linked command (with the FLAG bit set to zero) is complete and that status has
been sent. The initiator then sets the pointers to the initial state for the next
command.
If received by a target, this message is handled as an illegal message; the drive
enters the MESSAGE IN phase and returns MESSAGE REJECT.

This message is sent from the initiator to tell the drive that the last message byte
the drive passed on to the initiator contained a parity error.
To indicate that it intends to send the message, the initiator sets the ATN signal
before it releases ACK for the REQ/ACK handshake of the message that has the
parity error. This provides an interlock so that the target can determine which
message has the parity error. If the target receives this message under any other
condition, it proceeds directly to the BUS FREE state by releasing the BSY signal,
signifying a catastrophic error.
The target’s response to this message is to switch to the MESSAGE IN phase and
re-send from the beginning all the bytes of the message that precipitated the
MESSAGE PARITY ERROR message.

This message is sent from the initiator or target to indicate that the last message
received was inappropriate or has not been implemented.
To indicate its intention to send this message, the initiator asserts the ATN signal
before it releases ACK for the REQ/ACK handshake of the message that is to be
rejected. MESSAGE REJECT is issued in response to any message the drive
considers to be illegal or not supported. When sending to the initiator, the tape
drive does so before requesting any additional message bytes.
