There are of course many ways to skin a cat. In this case, xAP is one
of those possibilities...

The xAP HTTP server (both Windows and Linux) will allow bi-
directional comms via http out-of-the-box, simply by either hitting a
pre-defined URL or embedding a pre-defined tag. It can do this
underneath another web server of your choice if required. You will
need to build (or modify a pre-existing) connector to flavour serial
comms for your camera.

You can find the xAP HTTP server here: http://patrick.lidstone.net
(follow xAP projects, HTTP cache link, this will wrap:
http://patrick.lidstone.net/ha/xAP/xAP%20Projects/Applications/cache)

For the connection to the camera end, I suggest you look at modifying
something like the LCD/VFD interface to drive serial comms (assuming
you need output only), or the GSM interface if you want it
bidirectional.

If you only need to send stuff towards the camera, then you don't
need xAP HTTP at all - you can simply call "xAP-send" from a cgi
script, and it will fire off the relevant message to be picked up by
one or more of your camera connectors.

The Yahoo groups xap-automation list will help you out if you need
further enlightenment. More resources can be found at
