RF modems remain synchronized without use of master/server
dependencies. Each modem shares the roles of master and slave.
MaxStream's peer-to-peer architecture features fast synch times
(35ms to synchronize modems) and fast cold start times (50ms
before transmission).
Use default values for all modems.
