+/** This is a class for communicating without a Multi-Tech Systems SocketModem iCell. Instead, 
+* it uses the hayes command set to implement the same commands and functions as the UIP class.
+* (See the UIP class and documentation, "UIP.h")
+* This class supports three main types of cellular radio interactions including:
+* configuration and status AT command processing, SMS processing, and TCP Socket
+* data connections. It should be noted that the radio can not process commands or
+* SMS messages while having an open data connection at the same time. The concurrent
+* capability may be added in a future release. This class also inherits from IPStack
+* providing a common set of commands for communication devices that have an onboard
+* IP Stack. It is also integrated with the standard mbed Sockets package and can therefore
+* be used seamlessly with clients and services built on top of this interface already within
+* the mbed library.
+* The default baud rate for the cellular radio is 115200 bps.
