Hello,
I described the problem in
http://forum.arduino.cc/index.php?topic=279021.new#new and got some answers in

RECAP:I want to use ethernet shield R3 and GSM shiled R3 on MEGA 2650 an get control characters in the serial comm window when I put GSM shield on top of the ethernet shield. When I remove the GSM shield the server part works fine.
Somebody answered in http://forum.arduino.cc/index.php?topic=217423.new#new page 3.,  that i am using the wrong ports with the MEGA but the ports I use in the sketch mentioned in the first link is Serial. I think this is on pin 0 and 1. Do I only have to change the Serial.begin..  to e.g. SoftwareSerial mySerial(10, 11); // RX, TX.
And what about the connection of pin 10 to pin 2 and bended the GSM shield pin 2 ??


 ps. The ethernet board has a six pin connector SPI

 ps. The ethernet board has a six pin connector SPI  and is on the Mega. The GSMs  shiled is on top of it.
I also get the wrong answer in the ser. comm. window: "server at 0.0.0.0" with the "server" program from Tom Igoe and david Mellis. The server IP is identified when there is no GSM shield on top of it!
I read that the MEGA also uses pin 10 for the W5100 selection and apparently I also need this pin for the GSM shield...    Please help

Don't use D10. What is wrong with D11? Or D12? Those are GPIO on a Mega.

BTW, you aren't going to get much help with a subject line like that. You should edit it to something more meaningful.

I'd merge the cross-postings, but
a) I can't be bothered.
b) the forum software doesn't allow me to.
