to.
A
space
must
be
typed
after
the
"c"
and
on
both
sides
of
the
"v",
but
digis
are
separated
by
commas
and
no
spaces.
A
path
can
also
be
used
with
the
Unproto
command:
u cq v nom,lch,sli,bix
Unproto
sets
up
the
path
for
anything
that
is
subsequently
typed
in
the
Convers
Mode
where
no
connect
exists.
Connect
issues
a
connect
request
to
the
specified
station,
via
the
specified
path.
Then
an
error-free
conversation
can
take
place
between
them.
When
digipeating
the
packet
goes
all
the
way
from
the
first
station,
through
all
relay
stations,
then
to
the
destination
station.
Then
the
response
also
has
to
take
this
same
path
in
reverse.
Chances
for
collisions,
therefore
retries,
are
multiplied
with
every
digi
used.
This
is
often
called
end-to-end
acknowledgment.
Another
way
to
get
from
one
place
to
another
is
to
connect
to
a
"node".
A
node
will
take
care
of
the
acknowledgment
between
it
and
the
next
node
or
end
user.
See
the
KA-NODE
section
for
more
information.
Ask
your
local
packeteers
about
other
kinds
of
nodes
which
may
be
in
your
area,
such
as
TheNet
and
NET/ROM.
Gateway
In
the
KAM
and
KPC-4
a
Gateway
is
also
available.
This
is
similar
to
digipeating
except
that
the
retransmission
of
the
packet
takes
place
on
the
other
radio
port
of
the
TNC
from
where
it
was
received.
In
other
words,
if
you
are
on
VHF
and
send
a
packet
via
a
Gateway
callsign
of
a
KAM
your
packet
would
be
retransmitted
on
HF,
on
whatever
frequency
the
radio
connected
to
the
KAM
is
set
for.
When
you
use
one
of
these
gateways
remember
that
on
HF
the
baud
rate
is
slower
so
you
may
want
to
lengthen
some
of
your
timing
parameters.
See
the
KA-NODE
section
for
another
way to accomplish this with a more reliable connection.
The
TNC
has
some
parameters
that
need
to
be
set
before
this
feature
can
be
used.
The
MYGATE
parameter
needs
a
callsign
that
is
different
than
any
other
callsign
parameter
and
GATEWAY
needs
to
be
turned
ON.
Also
keep
in
mind
that
gateway
operation
is
not
permitted
by
FCC
rules
and
regulations
in
an
unattended
station.
Multi-Connects
The TNC makes it possible for you to talk to more than one person at the same time,
if you want to. A stream (or channel) is used for each conversation. The command
MAXUSERS determines how many streams may be used at one time. And the
command USERS determines how many people can connect to you. An incoming
connect uses the next available stream. If the number of streams set by USERS is
full, then that station will get a busy message instead of a connect. However, if
MAXUSERS is set larger than USERS, you can still issue outgoing connects on the
additional streams.
The character specified in the STREAMSW parameter is used to change from one
stream to another. The streams are lettered A - Z. So in order to change streams you
type the STREAMSW character and then the letter designator for the stream you want
(no return or enter in this case). This can be done in Command or Convers Modes and
the CON and STA lights on the front panel of the TNC will change appropriately for
the stream you choose.
For an example, let's assume I'm using a KAM and have my HF streamswitch set to
the "\" and the VHF streamswitch set to "|". Now if I want to transmit on HF packet,
I simply enter "\a" to cause my current I/O stream to be the A stream on the HF port.
