I know there are plenty of shell examples of something like this out there. If the program doesn't have an option of sending something on a set time you'll probably have to build it yourself. I've done this in the past by creating a file either with the timestamp as the name or its contents containing a timestamp. The format of the timestamp and frequency of the messages is something that you will have to devise.

I have to gather that this only pertains to the wireless network and a connection to the world is still assumed? Otherwise the whole thing is an exercise in futility. If it does have a connection to the world, what then determines that the wireless is down and not the net connection?
