Hi, I am really hoping someone from UniPi can help (and is even monitoring this thread). I have the USB Serial-1Wire cable from UniPi for the Neuron S103 and have yet to find the correct recipe to get this working.
I have used minicom on my Mac (Sierra) and Linux box (Ubuntu 16.04) 115200 8N1 no HW or SW flow control and even after I make sure enable_uart=1 is in /boot/cmdline.txt (per this: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/enabling-serial-console) I cannot get any login/boot output from the UniPi neuron. Note that I also try screen on both Mac and Linux and cannot get that working, meaning it opens the /dev/cu.usbserial (Mac) or /dev/ttyUSB0 (Linux) but I never see any screen output or login. Could it be the cable? Note I have also tried stty -F /dev/ttyUSB0 115200 and then cat -v /dev/ttyUSB0 as I am booting the UniPi and I dont see anything. Is there something else I can try? Thanks.

@Giamba I see that you are posting C source. I have found python in /usr/bin but I do not find any gcc or make anywhere. There is also no java installed. I am not an RPi user (I use nV embedded systems) so am not familiar with Jessie ... do I need to install these programming runtimes and environments? Do you know what size SD card I need to get to this environment?

Hi, I have the UniPi Neuron and I am trying to configure my Mac or Linux system for minicom to get a serial console. I have the USB-RJ11 cable from UniPi. Has anyone done this? I do not see documentation on parity, rate, etc and what are the login credentials? Anyone know the serial device settings? When I try with screen and ttyUSB0 screen exits immediately. Thanks.
