If the master is programmed to relay messages, then nodes on the multidrop can engage in virtual slave-to-slave transfers. Half-duplex protocol operates on a multidrop link with all nodes interfaced through half-duplex modems. There may be from 2 to 255 nodes simultaneously connected to a single link.
