I've been assigned to a project that I think is pretty cool. The main idea is to build two computers that will constantly communicate to each other (mainly to see if the connection is up) every 5 minutes or so. One of the computers will be in a remote location using a satellite connection that you can't trust.
What I need to do is setup a fall back system to use the cellular network as soon as the sat connection goes down. I guess I could use some sort of short-code in a SMS text message so it sends status and instructions from one computer to another.
What I don't know is what to do in order to integrate the computers with the GSM network. I know I can use a PCI modem and a wireless GSM interface (also known as telular) but I don't know, in case I could use one for this purpose, what characteristics should it have in order to interact properly with the computer. As far as I know there are some models with FSX which have a dialing tone (which I guess would be useful).
Thanks in advance!
