## Serial/RF bridge Broadcast

This parameter only has a meaning when operating in bridge mode.

When a serial port is operating in "Serial/RF bridge" mode, the packets received by the Viper from the serial port are sent over RF to all remote Vipers so they can pass this data over their corresponding serial port. This is achieved by the sending Viper by using a broadcast IP address. Upon reception, the remote Viper will pass this data over its serial port AND optionally send the data over its LAN port.

### RF Only

When receiving Serial/RF bridge data from a remote Viper over RF, pass it to the corresponding serial port and do not copy the data over the LAN port

When transmitting Serial/RF bridge data to remote Vipers over RF, do not send a copy on the LAN port.

### RF and LAN

When receiving Serial/RF bridge data from a remote Viper over RF, pass it to the corresponding serial port and send a copy of the data over the LAN port

When transmitting Serial/RF bridge data to remote Vipers over RF, send a copy over the LAN port.
