The tweener was never intended to be used with a standalone robostix.
The data coming out on the UART-0 pins is logic-level serial. You'll
need a serial adapter like the one of the ones on this page:

http://docswiki.gumstix.com/Serial_adapters> in order to see the data
on your PC.
Also, be sure to read this page:
<
http://docswiki.gumstix.com/Serial_voltages>
to understand the differences between the various voltage levels.
