5. A method of allowing multiple slave host computers on the same data radio communication network to communicate simultaneously, comprising the steps of:
-
linking a master host computer to a radio communication network directing data messages on the network;
receiving and repeating any data messages at a master host computer that are not intended for the master host computer from any slave host computer; and
transmitting repeated messages from the master host computer are received by all slave radios in the radio network by the RTUs to thereby allow communications between multiple slave host computers and RTUs on the radio network.
