* 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.
