Table 7 Response to

Initiator Detected Error

Linked Command

Complete (0Ah)

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 SuperLoader enters the MESSAGE IN phase and

returns MESSAGE REJECT.
