Responses Longer Than 256 Characters
If the response containing the read data is longer than 256 characters, the response is divided into
multiple frames as shown below. Only the final response frame ends in a terminator (*CR). All other
frames end in a delimiter (CR).
When the ID Controller sends any response frame except for the last one, it will wait for the host device
to return a delimiter (CR). When the ID Controller receives the delimiter, it will send the next response
frame.
