10.5.3.  Using Modem Library  
 
Figure  provides the architecture for Modem Library access. 
 

  

 

 

Modem Library provides the most complete modem access services.  In addition to the features 
already provided by the Messaging Library, the modem library maintains a modem parameter 
database.  In order to maintain the parameter database, the modem library requires more 
memory than the other libraries.  This makes the library unsuitable for some of the micro 
controller programming.  However, it is a good library to use by applications in a personal 
computer or a PDA.  It allows the programmer to develop host applications for the modem 
quickly. 

 
 

11.  Setup and Initialization 

 

 

The GPRS modem is controlled through the Modem RS232 port on the development board.  
Connect a nine pin straight through serial cable from the Modem RS232 connector to the serial port 
on the controlling computer. 
 
Hook up power supply, connect antenna, and install SIM into modem. 

 

 

The following provides an example for setting up a Windows HyperTerminal session that can be 
used to experiment with various configurations on the Enabler II-G A-GPS module for controlling 
computer:
