detect mobile phone and send SMS by it

[Sara]

HI,
I want to code a program to detect GSM mobile (any kind) which connected
through serial port to computer and then be able to send SMS through
this mobile phone to other mobile phones, could anyone help me and guide
me, I wrote a program which could open COM port but still couldn't
detect mobile phone and send SMS through it. I searched internet and I
didn't find right answer to my question.
please if anyone could guide me.
the programming language which I could use is VB.net or C#.net
I need to send SMS through web pages but we don't have any SMPP server
therefore I should and I must use this mobile device for my connection.
please if anyone could guide me.
In short
because I don't have other way, I should use this mobile which connected
to server computer where my aspx pages will run. and send SMS by it to
other mobile phone devices.
therefore I need first to detect this mobile phone which connected
through serial port to my computer then by using webservices or other
method through aspx pages, send SMS by this mobile.

There are three approaches you can take:

a.) I am not sure what your Device is - but Nokia has a developer
toolkit that as an ActiveX control which allows you to send SMSes using
their handsets. Check on the Nokia site. If you are using a Windows based
mobile phone (such has pocket pc phone edition), you can write a program on
your device (e.g.
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnppcgen/ht
ml/introappprogsms.asp) which in turn can call a web-service on your PC to
check for a flag to send SMS periodically.

b.) There are web-services that allow you to send SMS messages. You
typically need to pay the site whose services you are using a monthly fee. I
don't have the URL handing but a quick google search should turn up some
sites.

c.) You can go for a integrated hardware solution using a GSM Modem. The
charges per outgoing SMS will be same as charged by the cellphone provider
at given location (e.g. I pay Rs. 2 per SMS on hutch). Take a look at
http://www.xtendtech.com/ - they are few companies like this offering this
service..i hope i've cleared some hurdles, because this is wat we searched.

Download the API programming documentation for the GSM phone that you
are using. It will contain the commands that the phone uses. These
commands can vary among manufacturers. Siemens and Motorola have good
documentation and even sample code. To detect the phone, you need to
send an AT command that returns the text "OK".
