Responses Longer Than 250 Characters
If the response containing the read data is longer than 250 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).
By default, each response frame is separated by 20 ms. The interval between frames can be changed
using the PARAMETER SET (SP) command.
