This failure happens when trying to do Communications | Get data from Radio or Communications | Send data to Radio. The program presents this error message:
This is corrected by turning off the TNC which has control of the PC port through which you are attempting to program the radio.
Let's look at the signs on the radio
When you turn on your radio there are two things to watch for. The Opening TNC message will not remain, but, the "D" on the first line will. If that "D" is displayed, the TNC is On and in the way.
Press the 2-button on the face of the radio. Pree it just enough that you hear a single tone and the "D" disappears from the radio's face. Also, the Opening TNC will not appear if you power off and back on.
With the TNC off, you are ready to Get data from or Send data to the radio.
