This is only possible, if the sync managers are directly besides each other in memory. A fine solution for this would be to tell the master to check, if an existing FMMU could be extended before reserving a new one. This is currently not implemented. But feel free to do so! ;-) -- Best regards, Florian Pose http://etherlab.org _______________________________________________ etherlab-users mailing list [email protected] http://lists.etherlab.org/mailman/listinfo/etherlab-users
