Connecting Arduino to a USB GPRS Modem

Oleg has written up a project detailing how to get your Arduino talking to an inexpensive USB cell modem (~$25 from DealExtreme, among other retailers).  It’s based on a BenQ M23 GSM/GPRS wireless module and uses a standard AT command set.

This is the cheapest we’ve seen for a plug-and-play cellular solution, so it’s definitely a good resource.  His site walks you through the setup process and provides example code plus a complete library, so if you’re looking to do something similar, check it out.
