Every evaluation or development kit should have a Getting Started Guide.

As per my understanding you should do following :

1) Setup minicom with proper setting for BPS and where the USB to Serial
converter gets attached
    on host.
2) After you save the settings and exit minicom should read the data from
the sensor kit and display it
 on the terminal.

Why ? I think the sensor will capture/produce the data and will through it
to the serial port. MEMS should act as input device here.

Usually MEMS should be connected to at least 4 LED's to act as 4 direction
and when the sensor is moved it should light up the LED in that direction.
This might be the best way to test it.
