What should happen is it shows green thinking there is a connection. Within
10 seconds, it probes the interface to see if it replies right. If that
fails, the connection turns red. You should do a cut/paste of the console
log again so we can see that the port opened ok. Typical issue at this point
(assuming the open worked) is the baud rate doesn't match.
Now my next question is to confirm which make of interface and command
station you are using. That will help clue me as to the next things to try
to explain. The current console log will tell me what you are trying, but
that might not be the right match for the hardware you have.
