Well, I got it working (for a short period) and the problem was in the serial out and serial in portion but there is something strange. I my code, I have serin2 as portc.4 and serout2 as portc.5. I pinned these to the PINK module on the serial in and serial out pins. The strange thing is when they are pinned correctly (i.e., serout to serial out and serin to serial in) it doesn't work. After being frustrated for many hours, I swapped the pins and now it works fine. What I think they meant was serial out needs to go to serin and vice versa......ultimately I was at fault but certainly confused by the documentation.

After working for a few hours on it last night, it doesn't work any more. I was messing with the IP settings and now I can't communicate with it anymore. I'll call Parallax today but does anyone know if there is a reset function? There is nothing in the documentation and I want to reset it to a default state. Otherwise, this is a great product....I can see some really interesting projects.
