How to acknowledge that SCPI commands is sent and performed its function in TBS2014B Scope

Hi
We are doing Scope automation. sending command to load the setting file from USB to Scope. after sending command how do we know the file is loaded successfully.
is there any command to read the response?

in one of our test case, after the scope trigger I have to capture screenshot.
If the Scope is triggered for an event. how do I know that the scope is triggered? 

Thanks,
Sowmya
