4/ query commands
A special character can be used to query the device about its settings :
‘?’
Æ
What is the device’s current value for the setting(s).
Tag Field Usage
When a query is used in place of a Tag field, the query applies to the entire set
of commands available for the particular storage table indicated by the Storage
field of the command. In this case, the SubTag and Data fields should not be
used because they are ignored by the device.
SubTag Field Usage
When a query is used in place of a SubTag field, the query applies only to the
subset of commands available that match the Tag field. In this case, the Data
field should not be used because it is ignored by the device.
Data Field Usage
When a query is used in place of the Data field, the query applies only to the
specific command identified by the Tag and SubTag fields.
For example :
We want to know the current configuration for Code39 symbology :
The corresponding TAG is
