I recently purchased the Arduino GPRS Shield. I have connected it to a Arduino Uno and have followed the wiki and was able to send a text message via hardware UART. The problem is I tried following the first sketch (serial software) but I am unsuccessful at obtaining results. For some reason I am able to TX but the arduino does not show results on terminal. I have used hyper terminal, teraterm, and bray’s terminal. What am I doing wrong? Am I wiring incorrectly since I am using a Uno instead of a Duemilanove?
