10.4.1 Query and Update 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 available. 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.
