The addressed SLAVE will respond with an AN-
SWER whose structure depends from the MESSAGE
type.
When the MESSAGE is a reading command, the
SLAVE will respond transmitting a string with the
same structure of the MESSAGE.
NOTE
Using the RS 485 interface, the message structure
remains identical to the one used for the RS 232
interface, the only difference being that the value
assigned to the ADDRESS <ADDR>
