standalone suspend_data

I am attempting to test some JavaScript that communicates with some custom services without launching the SCO from an LMS.  (I am serving the SCO from a local Apache instance.)  I figured out that I can change the following line in Configuration.js to provide all the method calls so that no "method not found" errors occur:

strLMSStandard = 'AUTO'

Without an LMS, I confirm that the variable is effectively set to "NONE" and NONEFunctions.js is used for all the LMS functions.  This is what I wanted.  However, I did want to see the suspend_data set, which I don't think requires an LMS to generate, and this is not occurring.  The value (of GetDataChunk()) is always the empty string ("").

Why?  What can I try next?

Thanks,
