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?
