in reply to The Door Server

I like the idea. Nicely done. I have one question: Why use a barcode scanner if you could use a normal toggle switch attached to the door, linked to either the serial or parallel port. Would that solution make it cheaper? Typically those magnetic switches you get used by alarm systems should do the trick perfectly.

    I would have really liked to have done that, unfortuneately I do not know how to connect a switch to a serial port, nor how to monitor the activity of such a switch. Any resources (online or otherwise) for connecting things to serial ports, would be appreciated =)
