Serial Port on Beagle Board xM, revision C is not working.

[GoogleCodeExporter]

I am trying to setup Ubuntu on the beagle board.  When I use Minicom, with the 
settings set as per 
http://www.ibm.com/developerworks/linux/library/l-beagleboard-xm/
I get garbish characters.  This happens when I connect the USB to serial 
adapter directly to the DB9 connector on the board.  Also if I use the Angstrom 
version on the micro SD card supplied, I am unable to send and receive 
characters.

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?
I expect to see the uboot messages.  Using the same serial setup and 
development PC I see all the uboot messages from a mini2440 board.  My 
conlcusion is that the serial port on my xM does not work.

What version of the product are you using? On what operating system?
Version C

Please provide any additional information below.

I have a beagleboard-xm revC. I can work with a Pc and the beagle. The serial 
port is /dev/ttyO2 (letter "O" not the number 0 ) on beagle with ubuntu 12.04.
My problem is the serial port to communicate with trainerboard (Tincantools). I 
probe to communicate to /dev/ttyO1 but receives a sequence of bytes than not 
correspondign with tx data from atmel (arduino).
I need help.
Thank
