Request Information
| Byte | Data Field |
|---|---|
| NetFn | 30h |
| CMD | 94h |
| 1:3 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |
| 4 | Sub command, sub command = 1Bh |
| 5 | Parameter selector |
| 6:N | Configuration parameter data |
Response Information
| 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' state. (This completion code provides a way to recognize that another party has already 'claimed' the parameters) 82h=attempt to write read-only parameter |
| 2:4 | Manufacturer ID, LS Byte first. The length is fixed to three bytes. For example, if the vendor ID is 2011 and the corresponding hexadecimal value is 0x0007DB, the first byte is DBh, the second byte is 07h, and the third byte is 00h. |

| Parameter | # | Parameter Data | #(Decimal) |
|---|---|---|---|
| Set in progress | rw | data 1-This parameter is used to indicate when any of the following parameters are being updated, and when the updates are completed. The bit is primarily provided to alert software than some other software or utility is in the process of making changes to the data. An implementation can also elect to provide a 'rollback' feature that uses this information to decide whether to 'roll back' to the previous configuration information, or to accept the configuration change | 0 |
