 Hi elphel,

We have an NC353L combined with Garmin18 for GPS and ADIS 16375A IMU.  The
goal is to save pictures with known position and orientation (derivable
from IMU).  I've tried to get up to speed using the wiki and past e-mails,
but am still having trouble.  Here is my first question:

1) What is the data format of the imu data?  When running
    >> cat /dev/imu
    a series of non-ascii characters are printed.  Hence, either the data
is streamed in a binary format or the communication settings are incorrect.

If helpful, here are some outputs
  >> fpcf -imu 10000 | grep "0:"
