Create Source Route
Frame type: 0x21
This frame creates a source route in the module. A source route specifies the complete route a packet should
traverse to get from source to destination. Source routing should be used with many-to-one routing for best
results.
Note Both the 64-bit and 16-bit destination addresses are required when creating a source route. These are
obtained when a Route Record Indicator (0xA1) frame is received.
