Joe, Thanks for your response. See my responses embedded below IN CAPS FOR YOU TO SEE.

MY BREAKOUT BOX HAS RXD, TXD DTR AND RTS RED. IF I START CWTYPE WHICH USES THE DTR LINE FOR CW, WHEN I SEND FROM THE KEYBOARD, THE RTS LIGHT TURNS GREEN AND THE DTR FLASHES, AND THE K3 TRANSMITS AS IT SHOULD. WHEN I START N1MM (EVEN WITH RTS = OFF AND DTR = OFF) THE TXD AND RXD FLASH GREEN ON THE BREAKOUT BOX AND THE RIG'S TX LIGHT FLASHES ON AND THE RECEIVE AUDIO PAUSES DURING THE FLASHES. IF I CLOSE N1MM, THEN THE RIG RETURNS TO NORMAL. IF I START THE K3 UTILITY PROGRAM, NOTHING HAPPENS UNTIL I TEST COMMUNICATIONS AND THEN THE TX FLASHES AS WITH N1MM (BUT ONLY ONE TIME). IF I GOT TO TERMINAL TAB THE RIG FLASHES UNTIL I LEAVE THAT MODE (AND THE RXD AND TXD LIGHTS ON THE BREAKOUT BOX FLASH) . SO I DON'T THINK IT IS A 'BAD ACTOR' - FOR SOME REASON SENDING AND RECEIVING DATA CAUSES THE TX LIGHT ON THE RIG TO FLASH. > > If that doesn't help, go here ( > https://www.eltima.com/products/serial-port-monitor/) and download the > monitor.
