If I recall correctly the command line is 'screen /dev/ 115200' where 115200 is the baud rate. See the man page as well. For the location of the header, see [1] (which is the official BBB wiki). In case you're talking about the BBB Wireless, the header is right next to/above the processor/mem (the big 'Octavo' chip), image at [2].
