TNC), and the letter designation of the stream you wish to be on. No return or en-
ter key is necessary.
Note: Kantronics’most recent multi-port TNCs (e.g., KPC-9612 Plus) use only one
stream switch character and a number to specify which port and which stream to
switch to. See example below.
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
NØGZZ 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 occurs. Turning this command ON will make the stream de-
signators show on every connected packet received. Turning STREAMCA ON
will also add the callsign of the “from” station beside the stream designator.
Round Table Discussions
Several people talking together present a difficult situation for packet radio since
the protocol requires two stations to connect in order to make sure they receive
each others’ packets. If you wanted to be absolutely sure that everyone got every-
thing you said, you would have to connect to each person and retype everything
to each person. That could get a bit cumbersome, so most people use the Unproto
Mode and are aware that a collision may occur once in a while. You can usually
tell by the conversation if something was missed; if you don’t get an answer to a
question it’s probably not that he is ignoring you, but either the question or the
answer was corrupted by a collision.
