Serial log is on by default. Make sure you serial port parameters are setup as 115200,n,8. Don¹t enable xon/xoff and disable DTS/RTS handshaking. This won¹t stop the BBB from sending data, but it will prevent you from sending data back to the BBB. BTW, some of the tty-USB adapters don¹t always work. I have a cheap one that didn¹t work. The one recommended by BeagleBoard is the one I use and it works fine.
