Fields

Fields can be created by dragging a native type, enumeration or protocol from the Protocol Explorer to the list of fields.

The fields are serialized in the given order without any padding bytes. Fields can be scalar types (integer, Boolean, floating point) or arrays of scalar types.

Fields can also be Enumerations (see above) or other Protocols. In that way, complex datatypes can be created.

The list of Fields can be filtered and sorted by
