Wait for message SMS message to arrive.
When it does, move it to the controller.
Parse the message to identify which item to switch, and whether on or off.
switch item on or off.
go back to waiting
definetely you can do it, without doubt...
and this project has been discussed many a times in this forum toooo... do a search in the forum and you will get many solution.. if not clear then post
the controller you wish to use? the IDE and compiler to be used? The programming language to be used?
you may get a gsm modem and connect it to PC and play it with for a while and understand its working. and then write a program to interface with modem... you can download at command pdf from net or from this forum and play with the modem till you become friendly with it.. did you think about the gsm module you wish to use.????? do you have one or will get it...
there will be many outlets from where you can get one... you can get wavecom modem or simcom 300 basic modem for all the functionality
you can visit Sunrom Technologies, Your Source for Development or N S K E L E C T R O N I C S and select a modem yourself
guys I decided to use My Nokia 7110 since I have found it's AT-commands. take a look at this link.. I hope i can do it..
what's the difference between Uart, RS232 and serial communication??
Just make sure that the cable is serial not USB.
I found the below link and it shows that the cable is USB. You won't be able to interface it to your controller.

and make sure you test it in desktop and avoid testing in laptop... preferreably with XP facility and not win7 as OS as it does not support hyperterminal.. you can use other software instead of hyperterminal, but h recommended as it is hyperterminal is proven and stable

UART is an feature that defines the data exchange between devices... its present in every controller which gives out tx and rx and other control signals.. the UART transmits and receives data at a predefined baud rate specified by the user.
RS232 is the name of the cable used to connect 2 different serial port on different devices.
Serial communication is the protocol used by UART and many other data communicating devise , which define the number of data bits , number of stop bits, and parity, hardware flow control and the baud rate parameters....

Since it uses F bus for communication tapping tx and rx may not be sufficient. you may need a f bus to rs232 converter, or take tx rx and gnd and connect it through MAX232 ..
