Bug with DelimiterBasedFrameDecoder + Delimiters.nulDelimiter() orI am doing it wrong?

[miarkus at tlen.pl]

Hi!

What actionscript version are you using? 2.0 or 3.0? There was (and I'm not 
sure if it's still an issue) a known null byte issue with AS 2.0 regarding 
the null byte.
That was the reason why I had to port my AS 2.0 application to AS 3.0.
Also instead of using XMLSocket object you can use raw Socket class (AS 3.0) 
that will give you more control over sending data.

Best

Pete
