Yeah, a RPi does seem a little easier and common to work with. Once all the kinks are worked out with the steps, I will see what I can do to update the wiki.

So I just did a quick test by connecting a RPi to the BBB UART1 (P9_24 = TX and P9_26 = RX) after enabling the UART and confirming its available via: <code> root@beaglebone:/dev# ls -l ttyO* lrwxrwxrwx 1 root root 5 Jul 8 01:09 ttyO0 -> ttyS0 lrwxrwxrwx 1 root root 5 Jul 8 01:09 ttyO1 -> ttyS1 <\code> I logged into the RPi and started a minicom session with a 115200 and 9600 baud just to see if I can grab any response from the port. I believe you are correct that a console is not tied with UART1 since I'm not receiving anything of interest (no login prompt or even garbage). To farther verify this, I was able to make a console connection from BBB UART1 to RPi. There was no odd ball junk popping out like it would if using UART0 while tied to the console. On a side note, why is there a ttyS* tied with the ttyO*? I'd always assumed that those where devices indicating that there is a shell console tied with the UART port. After this quick test, it would seem like this is incorrect to assume. I was able to use either ttyO1 or ttyS1 to communicate from BBB to RPi without any issues.
