| Byte | Data Field |
|---|---|
| 1 | Completion Code 80h=parameter not supported. 81h=attempt to set the 'set in progress' value (in parameter #0) when not in the 'set complete' sate. (This completion code provides a way to recognize that another party has already 'claimed' the parameters.) 82h=attempt to write read-only parameter |
