INSTRUCTIONS
Packet

Connect Alarm
The
command
CBell
ON
will
cause
a’bell’
character
(~

to
be
sent
to
the
terminal
each
time
a
connection
is
established.
Packet
Formatting
eens
The
maximum
length
ofa
packet
is
determined
by
the
command
Paclen.
If
you
type
more
than
the
maximum
number
of
charac-
ters
without
entering
a
send-packet
character,
the
packet
con-
troller
will
transmit
a
maximum-length
packet.
In
Transparent
Mode,
a
packet
will
be
sent
if
the
maximum
number
of
charac-
ters
is
entered
before
the
delay
conditions
set
by
PACTime
force
a
packet
to
be
sent.
(Older
controllers
may
not
accept
packets
longer
than
128
characters.)
If
you
have
set
the
send-packet
character
to
<CR>
,
you
probably
want
the
<CR>
to
be
included
in
the
packet
for
display
at
the
other
end.
If
you
set
the
send-packet
character
to
a
special
non-printing
character,
you
probably
want
the
charac-
ter
to
be
treated
as
a
command
only.
The
command
CR
controls
whether
the
send-packet
character
is
to
be
echoed
and
included
in
the
packet.
You
can
add
a
<LF>
after
each
<CR>
included
in
your
packets
by
setting
LFadd
ON.
If
the
other
station
reports
that
ines
are
overprinted
on
his
display,
and
he
can’t
remedy
the
situation
at
his
end,
you
can
enable
this
function.

protocol,
a
set
of

This
may
be

You
can
specify
the
“address”
to
be
used
for
unconnected
packets,
as
well
as
intermediate
digipeaters
with
the

command.
The
format
is
simular
to
that
of
the

The
default
address
for
unconnected
packets
is
CQ.
The
following
functions
may
be
useful
for
tracking
down
protocol
problems.
They
are
seldom
useful
for
ordinary
packet
operations.
The
error-checking
function
of
the
protocol
is
dis-
abled
for
monitored
packets
with
the
command
PASSAIL
If
you
set
PASSAII
ON,
any
“packet”
will
be
displayed
if
it
meets
the
following
conditions:
It
