Communication over UDP is not deterministic in general, but on a 'clean' network it will usually work. Are you aware of the PdCom library on etherlab.org? You can easily write a kind of communication process with it to push/pull data to/from other destinations/sources. -- Best regards, Florian Pose http://etherlab.org _______________________________________________ etherlab-users mailing list [email protected] http://lists.etherlab.org/mailman/listinfo/etherlab-users
