I am in Puerto Rico right now, and don't have much time currently to look at my code (so far the
only Internet Access I can get is at work).  I don't know if I am pulling the 0x41 tables now that
I think about it.  Take a look at the "mythscan.c" code I wrote, and if this is the case then make
it pull te 0x41 table and see if this fixes the problem.

If I can get my GPRS to work tonight here I will log back in and take a look at my code.
