I am trying to connect the ADA Fruit USB to TTY cable to a Mac with Mac OS X 10.11.3. I installed the driver and see
/dev/tty.usbserial but when I try
screen /dev/tty.usbserial 115200 I get no output on the screen.
Any recommendations on how to wire the cable?
I checked a tutorial to verify whether I had to configure anything on the host side. It looks like I have
/dev/ttyAMA0 on ArchLinux, and
ls -l /dev/ttyAMA0 returns
crw-rw---- 1 root uucp 204, 64 Feb 22 09:40 /dev/ttyAMA0
note: I switched the cables in the right order before doing this.
/boot/config.txt. When I power off the Raspberry Pi 3 and disconnect the tty USB cable, reconnect the USB cable and power on the RPI 3 I get a boot message and login prompt but whatever character I type do not get shown on the display.
I followed the guidelines on the ArchLinux wiki to set up a serial tty. I typed
sudo systemctl status serial-getty@ttyAMA0.service and get,
* serial-getty@ttyAMA0.service - Serial Getty on ttyAMA0 Loaded: loaded (/usr/lib/systemd/system/serial-getty@.service; enabled; vendor preset: disabled) Active: active (running) since Wed 2016-03-23 12:12:15 EDT; 5min ago Docs: man:agetty(8) man:systemd-getty-generator(8) http://0pointer.de/blog/projects/serial-console.html Main PID: 218 (agetty) CGroup: /system.slice/system-serial\x2dgetty.slice/serial-getty@ttyAMA0.service `-218 /sbin/agetty --keep-baud 115200 38400 9600 ttyAMA0 vt220 Mar 23 12:12:15 stereos-pi systemd: Started Serial Getty on ttyAMA0.
Any pointers on what is happening or how I could debug this?
I did the exact same with Raspbian and I get a good working connection.
