Identify (80h or C0h)

Either the initiator or the CTS can send the Identify message. The

message is used to establish the physical path connection between an

initiator and the CTS.

When the CTS sends the Identify message to the initiator during

reconnection, an implied Restore Pointers message must be

implemented by the initiator before completion of this message.
