I have a app that sends me a text message to my cell when my pc starts up. i want to be able to send that app a "packet" or "signal" via the internet to control somesort of action like run a program or pop up a pre defined message or even shut the pc down. im not sure how to send packets or recieve them if its even possible, i know there will be some port forwarding needed on my routers end and i can do that part. Anyone know if this is possible?
