Short set of notes.

The most reliable way I’ve found to connect to a remote device is to open a connection immediately after connecting the USB cable to the PC.

At this time, I haven’t figured out a clean way to disconnect and reconnect without physically unplugging. Closing the screen session (ESC->CTRL+A->SHIFT+D->SHIFT+D) makes follow-up connections via the same line unreliable.

EDIT: This should work:

Connections require the Black GND (Ground), White TX (Transmit), Green RX (Receieve) pins connected. Connecting the Red VCC (Power) pin is STRONGLY discouraged.


# Find out what the USB device name is:
ll /dev/ttyUSB*

# Assuming it's ttyUSB0, connect to the device using GNU screen
sudo screen /dev/ttyUSB0 115200

Other methods:

And if you’re feeling silly, data can be send directly to the connected TTY like so.

echo "HEY YOU! GET OFF MY COMPUTER!" > /dev/ttyS0


I’m running Armbian (Ubuntu 14.04) on my Banana.
