The adapter has four wires, red, black, white and green. I looked up the USB standard and the white is D- (RX) and the green is D+ (TX) so I connected D- to PB0 and the GND to GND. Port COM4 where the adapter is cannot be opened. I moved D- to PB1 - PB4 in turn to see if there was any difference and there was none. Changed monitor_port to COM[1234] but no change but there was a different comment in the ouput:
— More details at Redirecting...
— Miniterm on COM1 9600,8,N,1 —
Don’t know if this has anything to do with my change.
