sync=true switch in fieldpoint address

I am working on software written by an ex employee, and have run across a string connected to the connection in terminal of a datasocket write function addressing a cFP-1808 DO module that I have not run across before. It does not generate an error, but I cannot determine it's purpose. The string is: \\10.0.1.105\FP\7DO\14?sync=true. I understand the part up to the 14 - 14th output of the DO module in slot 7, etc. What I don't understand is the '?sync=true' part. Can anyone help?

Thanks.
