| ParamID - | Index of the parameter to be updated. |
| VALUE - | New value for the parameter. |
Description:
This command assigns a new value to a writable system parameter. There is no reply packet. A parameter ID or value that is out of range will generate an error message. The allowable values for each writable parameter and what they mean are listed below.
This command saves changes of the writable system parameters to internal RAM, but not to the internal memory. The cmdVAL_SAV command writes these parameters to the internal memory.
