I don't really know what you're into with..
The link I posted above is a complete SMS alarm system using Nokia 6210 and DLR-3P interface with complete source code and operation instruction..
Also look here for complete DLR-3P circuit, pin-out and working HEX for DIY DLR-3P project..

Hi
Thank you for the link, I am using AT89C52 instead of PIC chips. I want to be sure with you that I am interfacing my AT89C52 with DLR-30's DBUS correctly:
AT89C52: TX (P3.1) and RX (P3.0) connect to Pin 7 (FBUS/RX) and Pin 8 (FBUS/TX) respectively. The Pin 9 will be grounded.
Do I need to add few resistors like the schematic in the link above?

Cortex said:-The TX(Phone) must be connected to the RX(AT)
-The RX(Phone) must be connected to the TX(AT)
-A I/O pin connected to the Mbus Pin
-That all
-No External resistor added for AT
-Resitor added for the Nokia are like the Pic Shematic.
You need to activate the Modem with the At before sending commands
