I am running Linux Mint 17.3 and fritzing 0.9.2. I can successfully upload a program to a picaxe 08M2 using the “Upload” button in the Code view.
However, when I click “Serial Monitor”, I get a “Device or resource busy” error. At the bottom of the Serial Monitor window, it says “Serial port open error”. In fact, it does the same thing if I disconnect the serial cable. However, I can confirm that I can read from serial out because I wrote my own python script to do so and it works. I have tried to configure the serial monitor, but clicking the “configure” button doesn’t seem to do anything.
Any idea what I am doing wrong?
Let me know if I need to provide any more info.
