GSM Modem Shield

The GSM Modem Shield for the Nebula has been an involved project. The hardware, based on the Telit GE865,  has proven quite successful. Writing a codebase has been the challenge. So far there is an extension for the command interface allowing both user program and command line control of the module. Functions to query time from the cell tower, signal strength, open and close HTTP socket connections, etc. are fleshed out. The first SMS ( text messages ) have been sent and received successfully. Code for sending e-mail is well underway as well. There is still much work to be done, but the progress is very promising.
