Using Format parameter you can signal to DatapacketReader in which
format expect data (dfBinary, dfXML etc)<br>
It is not required , when not set there is procedure which tests
"incoming" data using RecognizeStream method and select those
DatapacketReader, which is able handle "incoming" data.<br>
In other words each registered DataPacketReader is able say if is able
handle data in stream or not.<br>
(examines begining of stream and looks for own "format identification")<br>

Let me clarify. How do I SaveToStream from another TDataset descendant
and LoadFromStream in TBufdataSet?<br>
<br>
I am trying to call SaveToStream from some Delphi TDataset Descendent
to to be loaded by FPC's TBufdataSet.LoadFromStream. How should I do
it?<br>
</blockquote>
Can you try SaveToStream(..., dfXML) ?<br>
Because Binary formats are not compatible between Delphi and FPC<br>
But in XML should be situation better ;-)<br>
If you encounter any incompatibility please let us know ... (and attach
XML saved by Delphi + if possible any test application)<br>
