Field Definition
 Field length is in bits. '*' means that the length is variable and is set based on the
assigned value.
 Field starting offset is calculated from frame start based on the length of the pre‐
vious fields.
Examples:
Field32 : 32 = 0xAABBFFEE
FrameType : 8 = 12
HashedDest : 24 = HEX_DATA
Reserved1 : 8 = 0xDA
Field16 : 16 = 0xAAAA
Reserved2 : 8 = 0xAD
CRC : 32
Data field Definition
• Data = { pattern }: Pattern is assigned to Data.
• Data = count, value: A pattern of “count” times “value” is assigned to Data.
• Data = count, start value, step: A pattern of values starting with “start value” with steps of “step”
and a length of “count” is assigned to Data.
Primitive definition. Primitives are inserted into the frame payload. Primitive definitions
are inherited by descended frame templates.
 Assigning '*' clears all previous settings (maybe from parent frame template).
 Offset specifies the DWORD offset where this primitive is inserted in the Frame.
 Count specifies how many times to repeat the primitive.
Examples:
Primitive : *
Primitive : SOF, 48 # where 48 = offset
Primitive : "CLOSE (NORMAL)", 36, 5 # where 5 = repeat
Prolog and Epilog define Primitive chains to be used at the beginning and end of the
frame.
Examples:
Prolog = SOF # For this frame primitive 'SOF' is a Prolog.
Epilog = EOF # For this frame primitive 'EOF' is an Epilog.
Frames can be derived from other Frames, therefore inheriting the layout of the parent
Frame. In this case, the user may:
 Change Prolog and Epilog.
 Change default field values.
 Add new fields.
