Continuously send and receive data vodafone USB Modem

Hi. I'm trying to write a simple program to send and receive data from the vodafone dongle using HTTP requests. I tried modifying the Hello world HTTP client test example code provided in http://mbed.org/cookbook/VodafoneUSBModem but I have a few issues. I tried running the program continuously by terminating the previous thread and re-creating a new one but I get the blue lights of death on the second try /media/uploads/df611/httptest1.cpp Then I tried running an infinite loop in the thread while the main function just waits but I also get the blue lights of death. It works only when I declare the modem once in the thread and run the rest in a while loop as show below /media/uploads/df611/httpclienttest2.cpp . Now I have two questions: - Why terminating a thread in this program causes problems? - Why must the modem only be declared once? What's so special about this variable? Why can't it not be declared and removed like the rest?
