cmd:Connect N2WX VIA KAGFG
(Remember
to
use
actual
callsigns,
not
the
ones
in
the
ex-
amples.).
You
are
initiating
a
connect
to
yourself.
You
transmit
packets
to
the
other
stations
packet
controller,
which
relays
them
back
to
you.
When
the
connection
is
established
you
see
***
CONNECTED
to
N2WX
VIA
K4GFG
and
you
will
be
in
Converse
Mode.
Monitor
the
radio
transmit
indicators
and
listen
to
the
speaker
audio.
See
if
you
can
follow
the
packets
and
the
acknowledgements
back
and
forth.
The
other
operator
won’t
see
anything
cepiayee
on
his
computer
and
his
packet
controller's
state
won’t
be
affected
at
all
by
your
connection.
In
fact,
the
other
station
could
carry
on
a
separate
conversation
completely
independently.
Unsuccessful Connections
10
Sometimes
you
will
initiate
a
connect
sequence
that
can’t
be
completed.
The
station
may
not
be
on
the
air,
or
it
may
not
be
within
range
of
ire
station.
You
may
have
even
mis-typed
the
other
call
sign.
If
the
packet
controller
does
not
get
a
response
to
its
first
connect
packet,
it
will
try
again.
You
can
control
the
number
of
seen
the
packet
controller
will
make
with
the
command
REtry.
The
default
number
of
retry
attempts
is
10.
If
the
packet
controller
doesn’t
get
an
answer
after
this
number
of
transmissions,
it
will
give
up
and
display
the
message
*** retry count exceeded
*** DISCONNECTED
The
retry
count
is
also
used
once
the
connection
has
started.
Each
transmission
sent
to
the
other
station
is
“acknowledged,”
or
ACKed
by
the
other
station,
and
vice
versa.
The
ACK
means
that
the
packet
was
received
and
that
the
CRC
checksum
indi-
cated
that
it
was
received
without
errors.
This
is
the
means
by
which
packet
radio
can
ensure
error-free
communications.
Sometimes
a
packet
won't
be
received
correctly
by
the
other
station,
either
because
of
accidental
interference
from
another
acket
station
(a
collision),
or
because
of
other
channel
noise.
f
your
packet
controller
doesn’t
get
an
ACK
soon
enough,
it
retransmits
the
packet
and
increments
the
retry
count.
If
the
count
set
by
REtry
is
exceeded,
the
packet
controller
will
auto-
matically
disconnect
and
send
the
same
message
shown
above.
The
number
of
tries
may
be
determined
at
any
time
by
entering
the
command
TRles.
