Just started to look at your great program, I have used Arduinos in the past so just getting to grips with Pi (now I've retired).
I am working as a volunteer for the Solent Sky Museum in Southampton and we have several projects that Pi Presents will be great for, if I can get it all working!
Ok so my question is that I need to control an NEC projector on the serial port so that it turns on with the Pi and off at the end of the day. Input select is not a problem is there a way the GPIO can control the serial port? Its the usual 9600,8,n,1. In the past I have 'hacked' the remote control and used the IR to do this, but serial control via Pi Presents would be good any clues or tips would be appreciated.
