Hello Paulms, please excuse the late reply. If I have understood your questions correctly, you have no output to the terminal via the debug port.
Which windows operating system are you using?
Have you no output from the terminal which is integrated into LemonIDE?
In this case, when you want to use the serial terminal in LemonIDE, first you have to copy 2 dll files "rxtxParallel.dll" and "rxtxSerial.dll" into the windows system folder. Second you must copy the file "RXTXcomm.jar" into the java folder.
Does it work with the Hyperterminal?
Do you want to load programs via serial port into Eddy?
