[AG-TECH] projector control ?

[Luc Renambot]

The problem is to get the commands for the serial port.
On cheap projectors, usualy the manufacturer doesn't give
you the commands. 

When we built a tiled-display and an AG node in Amsterdam,
Philips gave us the commands going through the mouse port
of the projector. Writing a small library in C, you can then
wrap it in Python and control your projectors from a small script
or a web page (with Apache webserver, with python module).
It's so much easier to use a web browser than 20 ir remote
controls.
