Figure 7-6. BINARY Format 1
This data eld is initiated by a unique co de, the number sign (#). A
second byte, (2), designates the numb er of the bytes for the \No.
of the bytes transfer". \No. of the bytes transfer" designates the
data byte length. The last byte is zero (0), and has no meaning. The
response message terminator is, the EOI line is asserted while the
New Line (Line Feed) character (10 decimal) is being sent on the bus.
