PACKET CONTROLLER COMMANDS Command List
This is an immediate command. It resets all parameters to default
settings and re-initializes the packet controller.
To re-initialize the packet controller using battery-backed RAM
parameter values, use RESTART or turn the controller off and
on.
This command sets a minimum delay that is imposed on acknow-
ledgment packets. This delay may run concurrently with default
wait set by DWait and any random wait in effect.
This delay may be used to increase throughput during operations

maximum
number

packets.
Occasionally,
the
sending
packet
controller
may
not
have
a
packet

in
time
to
prevent
transmission
from
being

temporarily,
with
the
result

packets
collides
with
the
final
packet
of

RESTART
is
an
immediate
command.
It
re-initializes
the
packet
controller
using
the
defaults
stored
in
bbRAM.
The
effect
of
this
command
is
the
same
as
turning
the
packet
controller
OFF
then
ON
again.
RESTART
does
not
cause
a
reset
of
the
parameters
in
bbRAM.
See also RESET.
The
protocol
allows
for
retries,
i.c.,
retransmission
of
frames
that
are
not
acknowledged.
Frames
are
re-transmitted
n
times
before
the
operation
is
aborted.
A
value
of
0
for
n
specifies
an
infinite
number
of
retries.
If
the
number
of
retries
is
exceeded,
the
packet
controller
goes
to
the
disconnected
state
(with
an
informative
message
if
not
in
Transparent
Mode).

commands.
