are operating under special conditions, such as a marginal HF channel, you can
set RETRY 0 to disable all
automatic disconnects (the retry limit is never
reached).
Monitoring Channel Activity
In addition to displaying messages from the station you are connected to, the
MFJ TNC can allow you to monitor other packet activity on the channel. You
can "read the mail," displaying packets between other stations. The MFJ TNC
will also keep track of stations heard during a session. This section will describe
some of the monitor functions.
Monitoring is enabled or disabled by the MONITOR command. You can try
this out in digital loop-back mode while disconnected. Type:
cmd:MONITOR ON
cmd:CONVERS
This is a test packet.
K5FLU>CQ:This
is a test packet.
Since you aren't connected to another station your packets are sent to the address
"CQ," i.e., anyone. The packet you sent was "heard" by the MFJ TNC and
displayed, along with the sending station and the destination.
If you also want to see any intermediate digipeater stations being used, you can
set MRPT ON. This feature would be useful if you later want to connect to one
of the stations you are monitoring and will need a digipeater route in order to
reach it. For example, you might see the following display:
WB6YMH>WD0ETZ,KV7B:Hello, Bill!
This packet was sent from WB6YMH via KV7B to WD0ETZ.
If there are several digipeaters, or if the message lines are long, the display may
be difficult to read. You can put the address header on a separate line from the
text by setting HEADERLN ON:
WB6YMH>WD0ETZ,KV7B:
Hello, Bill!
