Drive
address
The
drive
only
acts
on
messages
received
that
contain
a
drive
address
if
the
whole
drive
address
or
drive
group
address
match
the
whole
address
or
the
group
address
in
the
message,
or
if
the
address
in
the
message
is
0
(i.e.
a
global
message).
Global
or
group
addressing
allows
data
to
be
written
to
more
than
one
drive
with
one
command.
The
drive
does
not
give
a
response
to
a
global
or
group
write
message.
Although
it
is
possible
to
perform
a
global
or
group
read,
this
would
result
in
messages
crashing
if
more
than
one
drive
responds
to
the
command.

The

is
aborted
because
the

menu

or

are
not
the
same
as

other.
3.
EOT
is
received.
4.
A
character
other
than
NAK,
ACK,
BS
or
STX
is
sent
as
a
short
command.
5.
A
character
other
than
ENQ
is
sent
at
the
end
of
a
read
command.
The
following
short
commands
can
be
used:
NAK
Not
acknowledge
(Ctl
U)
This
is
the
same
as
requesting
the
value
of
the
last
parameter
to
be
read
or
written
to.
The
response
is
the
same
as
for
a
normal
read.
ACK
Acknowledge
(Ctl
F)
This
is
the
same
as
requesting
the
value
of
the
parameter
after
the
last
parameter
to
be
read
or
written
to.
The
response
is
the
same
as
for
a
normal
read.
BS
Back
space
(Ctl
H)
This
is
the
same
as
requesting
the
value
of
the
parameter
before
the
last
parameter
to
be
read
or
written
to.
The
response
is
the
same
as

a

the

All
the
short
commands
will
only
read
from
the
drive
or
write
to
the
drive
if
a
valid
address
has
already
been
sent
to
the
drive
in
a

command.
The

is
registered
as
