Unproto sets up the path for anything that is subsequently typed in the Convers
Mode where no connection exists. CONNECT issues a connect request to the
specified station, via the specified path. Then a virtually error-free conversation
can take place between them.
When digipeating, the packet goes all the way from the first station, through all
relay stations, to the destination station. Then the response also has to take this
same path in reverse. Chances for collisions and, therefore, for retries are multi-
plied with every digi used. This is often called end-to-end acknowledgment. An-
other 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 types of nodes which may be operational in your area, such as K-Net,
TheNet, NET/ROM, G8BPQ, and ROSE.
+ Kantronics TNCs support additional, advanced UI digipeating commands. For a
description of Kantronics’ UI digipeating commands, see “Advanced GPS/APRS
digipeating”, in the GPS Mode of Operation section of this chapter.
Gateways
In Kantronics’ multi-port devices (e.g., Kantronics KAM Plus and KPC-9612
Plus), a Gateway is also available.
Using a gateway is similar to digipeating except that the retransmission of the
packet takes place on another radio port of the TNC other than where it was re-
ceived. 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 fre-
quency the radio connected to the KAM is set for. When you use one of these
gateways on HF, 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 an-
other way to accomplish this with a more reliable connection.
Multi-Connects
The TNC makes it possible for you to talk to more than one person at the same
time. Single port TNCs such as the KPC-3 Plus support 26 streams on the one
port.
+ Multi-port TNCs (e.g., KPC-9612 Plus) support 26 streams per port.
