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.=
