How to access GPM locally ?

I’m using the XBEE Pro SX (900Mhz) module. I’d like to access the GPM locally so that the host I’m interfacing to can store and read some configuration data. I tried the examples listed in XBEE Pro User Guide for OTA access without success. Also, my goal is to access GPM locally from the host microcontroller on the serial port.
Any examples or assistance would be appreciated.
Thank you,
