Kantronics' TNCs support additional, advanced UI digipeating commands. For a
description of Kantronics' UI digipeating commands, see ―Advanced GPS (or APRS)
digipeating‖, in the GPS Mode of Operation section of this chapter.
Gateways
In Kantronics' multi-port devices (e.g., Kantronics' KAM Plus, KAM XL, 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 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 on HF, remember that on HF the
baud 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.
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.
The command MAXUSERS determines how many streams may be used at one time,
per port, and the command USERS determines how many people can connect to the
TNC per port. An incoming connect uses the next available stream. If the number of
streams set by USERS is full, then a station attempting a connect with your TNC will
receive a busy message instead of a connect. However, if MAXUSERS is set larger
than USERS, you can still issue outgoing connects on additional streams.
To determine which port you are on, simply use the STATUS command, typing STAT at
the command prompt. The TNC will report which streams are active and which one you
are on. If you wish to remain on the current stream to communicate, no action is
necessary. To change streams ( to make another connect or to send data to another
station already connected to you) type the STREAMSW character, the number of the
port (if you are changing ports on a multi-port TNC), and the letter designation of the
stream you wish to be on. No return or enter key is necessary.
For example, let's assume you are using a KPC-9612 Plus and you are connected to
WØXI on stream A of port 2 but you wish to return to a discussion with NØGRG on
stream B of port 1. Whether in command mode or convers mode, simply enter ―|1b‖ and
the TNC will switch to port 1, stream B. When you do this, the CON and STA lights on
the front panel will switch with you, reporting the status of the new stream.
If you are connected and have MONITOR or MCON OFF, the normal headers
containing the ―to‖ and ―from‖ callsigns will not be shown. The setting of STREAMEV will
then determine how often you see the stream designator. This parameter comes
defaulted OFF, so the stream designators are only shown when a change in streams
