Hi,

you could download my package
http://www.ib-paus.com/downloads/AdaStreamsInNetworkByteOrder_020326.tar.gz
and use it with your program. This will automatically convert all data
into network byte order, so that you can work with mixed architectures.
This is a modified version of a standard GNAT package and so only works
with GNAT.

Hope this helps

Michael
