Sequence error. | Indicates a programming error. | |
|
| Slave programs must call the |

| ACEPT or REJCT, then call GET |
|
| again. An exception to this |
|
| would be after an error is |
|
| returned on the GET call, the |
|
| slave goes back to the GET call |
|
| again. The master program |
|
| must be the one to attempt any |
|
| retries. |
