Hi Wayne,

I followed your tip on fixing this issue, but it seems that I pin
pointed the problem a little bit more:


The FOXGM has a female connector, the FoxBoard too. Between them I put
headers, to connect both boards together. It seems that the 'headers',
the so-called BUS-strips, aren't working properly. How I figured?

When rearranging these headers (a headers can be put in two different
ways into the FOXGM, each header can be put in one of either
connector, so there are 6 combinations possible.) I noticed that in
one of the arrangements I can turn on the Telit Modem using "setbits".
I even lighten up a LED (Bit 29) using (setbits). Bit 28 seems to be
impossible.

What I don't understand is the logic! Is it possible for the pins in
the headers to be faulty? How come some arrangements work and some
don't? Got any ideas? 

Cheers!
