is it possible for me to intercept the text messages that get sent to my cellphone if i connect to my cellphone via bluetooth or USB or some other connection to my computer?
i want to create a database with all of my received text messages and be able to control my cell phone through my computer by using it to send text messages
i have a regular motorola flip phone
You can send text messages from your phone to your email address, and email messages to your phone number. I'm not sure if you could "intercept" the messages, but you could set up a smart mailbox that catches all emails with a certain tag or from a certain sender (your phone number).
According to GSM Specification 27.005 you should be able to get indication on incoming sms.
You need to open AT Command terminal to the phone (most of the times you do that by plugging the phone to the usb, and connect to the com port that was created for it).
The command that you are looking for is AT+CNMI. Just read the specification.
NOTE: Long time ago, I've tried to do the same thing using Nokia phone and it didn't work. The phone didn't support this feature.
