4.3.1 Header/Terminator Selection
The header/terminator selection is not effected by restore default command.
Header Position
This parameter defines the header position within the frame to be transmitted from
DLCC to the Host. The header can be positioned in either the first field of the frame
or in the field preceding the message:
FRAME
HEADER Address Address Delimiter MESSAGE
HEADER Time-Stamp Time-Stamp-Del Code Id Code Len DATA Terminator
The Address field has different meanings depending on if the FRAME is a 2 way
answer to a previous 2 way transaction initiated by a DLCC Client, or if it is a new
message that an RF device sends to the DLCC Server. See par. 4.3.2 for details.
