Using the AdaFruit FTDI Friend (https://www.adafruit.com/products/284 =
<https://www.adafruit.com/products/284>) is even simpler with the =
BeagleBone Black: just plug it directly into the J1 jumper mentioned =
above and everything lines up automagically. :-)

Once plugged in, connect it to your "serial terminal" (e.g., FreeBSD =
host system) via a mini-B to USB-A cable and use "cu" to connect.  Speed =
is 115200.  It even includes send and receive blinkenlights so you can =
see when data is flowing...

Cheers,

Paul.=
