An exclamation point (!) performs the com-mand’s operation on the device’s volatile menu configuration table.A period (.) performs the command’s operation on the device’snon-volatile menu configuration table. Use the non-volatile tableonly for semi-permanent changes you want saved through a powercycle.Query CommandsSeveral special characters can be used to query the device about its settings.^ What is the default value for the setting(s).? What is the device’s current value for the setting(s).* What is the range of possible values for the setting(s). (The de-vice’s response uses a dash (-) to indicate a continuous range ofvalues. A pipe (|) separates items in a list of non-continuous val-ues.):Name: Field Usage (Optional)This command returns the query information from the image scanner.Tag Field UsageWhen a query is used in place of a Tag field, the query applies to theentire setof commands available for the particular storage table indicated by the Storagefield of the command. In this case, the SubTag and Data fields should not beused because they are ignored by the device.SubTag Field UsageWhen a query is used in place of a SubTag field, the query applies only to thesubset of commands available that match the Tag field. In this case, the Datafield should not be used because it is ignored by the device.Data Field UsageWhen a query is used in place of the Data field, the query applies only to thespecific command identified by the Tag and SubTag fields.Concatenation of Multiple CommandsMultiple commands can be issued within one Prefix/Storage sequence. Only theTag, SubTag, and Data fields must be repeated for each command in thesequence. If additional commands are to be applied to the same Tag, then thenew command sequence is separated with a comma (,) and only the SubTag andData fields of the additional command are issued. If the additional commandrequires a different Tag field, the command is separated from previouscommands by a semicolon (;).
