5.4.3 Parameter Commands
Query commands are used to request established parameter values. There is a
specific query command for each parameter group. Depending on the actual
hardware configuration, the response to some Query commands may be an "E"
error code indicating there is no data to retrieve. Each command has one to three
arguments.
Update commands are used to change a specified parameter to a new value or
condition. Some parameters are order dependent in that they cannot be updated
prior to certain other parameters. There is a specific update command for each
parameter group.
The command variations include:
