Continuation SEND message frames
A continuation SEND message frame is started if the volume of data exceeds 128 bytes. The
sequence is the same as for the SEND message frame.
If more than 128 bytes are sent, the extra bytes are automatically transmitted in one or more
continuation message frames.
The figure below shows the transmission sequence when sending a continuation SEND
message frame with a continuation response message frame.
