Reading Multiple Bytes of Input, Output, or Register Data

being transmitted is shown as hex bytes from left to right in the order they are
transmitted. Generally the first byte is the target ID, and the second byte is the function

lengths, and data if applicable. The received data is shown in the same format. The data
bytes are bracketed by ––> DATA BYTES <–– left and right arrows.
