alarm modem interface

[aemx]

i am interested in the design of an alarm interface to a communications system and was hoping you could help.<br>
What my proposed system is meant to do is recieve an alarm alert and convert this to a text message then send it as an email to a specific computer(s). <br>
I figure i would be using a point to point protocol as the email pathway, but am having a bit of trouble designing the circuit, I think that the best way to get an initial system up and running would<br>
be through the use of maybe a mircocontroller and a modem attached.  Inputs<br>
to the unit from the home sensors would come in via the serial port.  (We<br>
would have a custom microcontroller monitoring your sensors or other<br>
inputs(s) and relaying this data to the single-board computer via the serial<br>
port.)  and a program would start that monitored the serial port.  When emergency conditions are<br>
met, a program would start running that performed an auto-dial and login to<br>
a local internet service provider.  Once this connection is established, the<br>
program will send an e-mail indicating the problem and perhaps what sensors<br>
had been activated, and then it will log off.<br>
Any pointers on the circuitry design would be greatly appreciated.<br>
I would like to thank you for your time<br>
Yours<br>

Sensaphone has a couple of units that do this. The 2000 and 3000. The 2000 is monitoring only. The 3000 is control also. The 2000 is reasonably priced and they claim it will E-mail. I have their config software and a copy of the manual somewhere on or near my desk. They have a web page.
