DTYPE [NODE/ROOT/GATE/PEER]

This command configures a radio's type for network-wide diagnostics.
For most radio systems, it is sufficient to define a radio as a root or node
radio. The root radio is the radio connected to the host computer for
non-intrusive diagnostics functions. Specify only one root per radio net-
work.
The and settings are used for complex radio networks and are
