Let's take this one step at a time.

You'll need to make a start with a program which communicates
with a serial port of some sort.

Are you going to write your own program, or are you looking for
something already written?

How will your modem be communicating with the computer? Will it
be using USB, a true serial (RS232) cable, or something else?

What operating system will the computer be running?

If you're going to be doing some programming, what language do
you prefer?

pls says some books to read the AT commands.....

That's not something I can help you with - maybe someone else
can?

But if you want help with specific "AT" commands, then I can
probably assist.

hello sir

thanks for the reply

i am looking to write my own software but like to see few example
before starting...

please assist me in at commands.....can u suggest me any books for thes
commands or any resources as i am start gonna learn i dont know anythin
about it

my system will run xp operating system.....(but is it any big change i
my system runs windows 7)

i am going to buy a modem with supports both usb and serial.....but
prefer to use serial cable(RS232)

is there is any emulation software to learn writing software t
communicate with modem....(i mean some software for testing...)or an
interface where i can write my own software....

i learnt that i can use java and At commands to communicate with mode
.....which is more powerful and easy to use...
thank

There's no lack of examples on the Internet. Someone I know is
using the Perl program suite mentioned on
http://grumpyoldprogrammer.blogspot.com/2009/07/home-sms-gateway-using-perl-ubuntu-and.html

Likewise, a google search for combinations of terms like "sms
java" brings up lots of promising hits.

please assist me in at commands.....can u suggest me any books for these
commands or any resources as i am start gonna learn i dont know anything
about it

Have you got a copy of 3GPP 27.007 and 3GPP 27.005? They're
freely available on the Internet. They're terse and technical,
but you can ask for further information here.

I repeat that I don't know of any books, and I'm sure you can use
google as well as I can to find any.

my system will run xp operating system.....(but is it any big change if
my system runs windows 7)

I can't really comment on Windows other than to say that it's
what most software will be designed for.

i am going to buy a modem with supports both usb and serial.....but i
prefer to use serial cable(RS232)

There's a serial programming guide here:

http://www.programmersheaven.com can also be useful.

is there is any emulation software to learn writing software to
communicate with modem....(i mean some software for testing...)or any
interface where i can write my own software....

On Windows, you can use Hyperterminal to communicate
interactively with your modem.

i learnt that i can use java and At commands to communicate with modem
.....which is more powerful and easy to use...

I'm sure Java is quite suitable, with lots of examples available
on the Internet. But it's not a language I use myself.

Hello,
the best would be to use the AT command specification of the particular
GSM Modem you want to use for your project.

Here for example you can find the AT Command spec for some
Siemens/Cinterion GSM Modems.

http://www.mc-technologies.net/wireless_modules/downloads.php

Some further links.

http://www.gsm-modem.de/index.html

A lot of todays GSM Modules are providing an internal API to run own
Programs on the Module itself. But this functionality is specific to the
current module. The Cinterion AC75 provides a Java Platform for own
Applications. Some Wavecom Modules are providing a C like API for own
apps on the module.

You should describe what you want to do. Do you want to use the GSM
Modem in an host system only as datapipe or do you plan to design a
small application which can run on the GSM Module itself.
