Just use a reasonable network data distribution protocol or some custom
serialization/deserialization method.
A protocol that uses 4 octets to transfer 4 enumeration states is not
reasonable by any count.
In any case, never use protocol representations to store application
data. This is an exemplary case of abstraction inversion.
