Length
This parameter specifies the number of bytes of the data block to read. If the

server data block length is less than requested, the length of the response will be

the actual length of the data block. If the server data block is greater or equal, the

response will contain the same amount of data.
The slave may answer with an error response if data access is not allowed.
