###LINK MADE
###CONNECTED TO NODE KC (NØAPJ-2) CHANNEL A
ENTER COMMAND B,C,J,N,X, or Help ?
At this point you are ―patched‖ through the KA-Node LAW to the node KC. When LAW
issued the connect request to KC it used your own call but subtracted a count of one
from your SSID. For example, if you connected to LAW with WØXI, LAW connected (via
your request) to KC with WØXI-15. This is automatic.
At this point, you could connect to another KA-Node, some other network node using
AX.25 as an uplink or downlink protocol, or to an end-user. Let's assume that you desire
to connect to NØKN. So, just enter in response to the node ―enter command‖ above:
C NØKN STAY
and you'll get the response:
###LINK MADE
We'll explain the ―STAY‖ later.
You are now connected to NØKN. If you have issued a connect command to a KA-
Node, and realize that you have made a mistake with the call, or for any other reason
wish to cancel the connection, you may do so by using the ABORT command. In order
for the abort to work, it MUST be the first word entered following the connect command
and must be spelled out entirely. For instance if you tell the KA-Node:
C KB5EEG
and then decide to abort the connect, your next entry must be:
ABORT
Any other entry will cancel any possible abort of the connection, and you must wait for
the KA-Node to retry out (e.g., because it will try to connect to KB5EEG).
Now that you are connected to NØKN, you can carry on a normal packet QSO. While
everything appears ―normal‖ and AX.25 compatible, acknowledgments to your packets
are generated by the KA-Node directly connected to you. Each link in the chain/pathway
takes care of its own errors. In other words, the link between KC and LAW handles its
own error checking. In this way, one weak link will not cause end-to-end packets and
acknowledgments to be repeated as they would with digipeating. The result is
substantial improvement in throughput for connections using nodes.
When it comes time to disconnect, you do so in the standard AX.25 manner. To
disconnect the link described above, type <Ctrl+C>, obtain the cmd: prompt on your
TNC, and issue the disconnect command:
cmd: D
