Defi ned Responses (slave to master)
There are three possible responses to a communication transfer initiated
by the master. These are a Simple Acknowledge, Acknowledge with Data,
and a Failure message.

Simple Acknowledge

If the received command does not require data to be returned, a simple
acknowledge consisting of an ASCII ' A ' will be sent.
Example:
Slave: A[CR]

Acknowledge with Data

If a command issued by the master requires data in response, an Acknowl-
edge with Data response will be issued. This response consists of an ACSII
' A ' followed by data and checksum.
Example:
Slave: A0123456A6[CR]

Failure

All failure responses consist of an ASCII 'N' followed by a two byte hexa-
decimal ASCII failure code. Defined failure codes are given in the table
below.
Example:
Slave: N01[CR]
