pathway is considered a connect and all acknowledgments of packets are kept local.
Hence, if only one link of a pathway (chain) is troublesome, the local nodes take care of
it.
The following material is provided to assist you in configuring your KA-Node and telling
others how to connect to and use it. A listing of the node commands for users follows.
Configuring Your KA-Node
The following commands are used to configure your KA-Node: NUMNODES, MYNODE,
NDWILD, and KNTIMER.
In order to set your TNC for use as a KA-Node several conditions must be met. First,
you must allocate the number of circuits (channels) you wish to allow through the KA-
Node (see NUMNODES). Each circuit consists of an ―IN‖ and an ―OUT‖ side. Secondly,
the callsign assigned to the KA-Node (MYNODE) must be different from the callsign
used for you (MYCALL), your alias (MYALIAS), the PBBS (MYPBBS), and remote
access (MYREMOTE). By default, your TNC has set MYNODE to your callsign with an
SSID of -7.
To cause your KA-Node to accept a connect request to any SSID of the MYNODE
callsign (except those mentioned above), set the NDWILD command ON.
Packets passing through your KA-Node are monitored unless your MYNODE callsign is
included in the SUPLIST, if turned ON. If it becomes necessary to disconnect a station
from your KA-Node, you can issue the command DISCONNECT MYNODE x (x =
channel) from the local terminal connected to your TNC.
If no data passes through an established (connected) KA-Node circuit for n minutes,
where n is set by ―KNTIMER‖, then that circuit will be disconnected. The default time is
15 minutes but you can disable this by setting n to 0.
Each KA-Node circuit allowed will require approximately 4.3 kbytes of memory. If you
attempt to set NUMNODES to a value requiring more memory than available, you will
receive a message indicating that the value is out of range. The total number of circuits,
which may be allocated, will also be affected by the amount of memory allocated to the
Personal Mailbox.
Some Kantronics TNCs, such as the 9612 Plus, are multi-port. These multi-port KA-
Nodes can support cross-connects, Xconnects; that is, users may connect on one
port and then connect out another port, which may be attached to another radio set
to a different frequency.
Using a KA-Node
The material that follows is meant for those using your KA-Node, i.e. connecting to it.
You may use this material as a guide to using someone else's node or in connecting
to your own node from another location (car, another station, via a digi, etc.).
