When it is connected that way, it is not called a
"dumb tracker"...

That is exactly why we have that category called
dumb-trackers.  It refers to any tracker that
only transmits and does not do messaging nor
any other display of "received" APRS data.
As you say, you are frustrated when you cannot
talk to one... that is why we call it "dumb".

When a KPS-3 or any other TNC is connected to
a computer or laptop, it is no longer a dumb
tracker but a "full-up" APRS system (unless it
runs some "dumb" software, but I wont go there...
