to if BUdlist is ON. Otherwise, the stations in the list will be
ignored, and all other stations will be monitored.
You can operate a group conversation with some data integrity
b having the stations connect in pairs and setting MAI] ONand
‘Con ON. This does not insure that every packet is received at
every station, but it does insure that a packet involved in a
collision will be retried. If you have an odd number of stations
participating in this sort of conversation, one station can connect
to himself via another station as digipeater.
Ordinarily, only text packets are displayed. If you desire to
monitor all packet activity on frequency including all of the
’supervisory’ frames that contain no user data, set MCOM ON.
This
allows
every
correctly
received
frame
to
be
displayed.
For
example:

You
can
cause
the
packet
controller
to
“filter”
certain
characters
from
monitored
packets
with
the
command
MFilter.
This
allows
you
to
remove,
for
example,
form-feeds,
bell
char-
acters,
or
clear-screen
characters
that
may
be
necessary
to
the
stations
involved
in
a
connection,
but
which
may
interfere
with
your
display.
You
can
specify
up
to
four
characters
by
giving
the
ASCTI
character
codes
in hex
or decimal.
The
command
PId
ON
will
eliminate
the
display
of
received
frames
whose
Protocol
Identifier
(PID)
is
not
$F0.
This
should
prevent
most
unwanted
NODE’
transmissions.
The
CON
and
STA
LEDS
can
be
made
to
indicate
the
condition
of
the
processor
in
place
of
their
normal
functions.
The
com-
mand
HEALled
ON
will
cause
the
two
LEDS
to
turn
on
and
off
in
a
sequential
Pattern
if
the
processor
is
properly
executing
the
software.
H.

returns
the
LEDS
to
their
normal
functions.
Twenty
five
counters,
all
of
them
16
bits
wide,
are
provided
to
monitor
a
number
of
parameters
in
the
packet
controller.
They
are
ALWAYS
initialized
to
0000

power
por
“RESTART”.
The
counters
and
the
setting
of
HEALled

LED)
are
displayed
in
response
to
the
command
DISPlay
