+ *   - no conn,
+ *   - NACK or R_ERR received in response to this command,
+ *   - credit blocked or not available, or in the case of SMP request,
+ *   - no SMP response was received.
+ *   In these four cases it is known that the target didn't receive the
+ *   command.
+ * TI - Task Interrupted, error after the command was acknowledged.  It is
+ *   known that the command was received by the target.
+ * TU - Task Unacked, command was transmitted but neither ACK (R_OK) nor NAK
+ *   (R_ERR) was received due to loss of signal, broken connection, loss of
+ *   dword sync or other reason.  The application client should send the
+ *   appropriate task query.
+ * TA - Task Aborted, see TF.
+ * _RESP - The completion includes an empty buffer containing status.
+ * TO - Timeout.
