Hi,

Can anyone help me with a link or circuit for the following:
I am wanting to build a small cabled remote control keypad with 2 or 3
buttons to control a PC during powerpoint presentations without having to
have the mouse or keyboard on the lectern. I have seen these before but the
only types i can find on the web are IR types.
Ideally i would like it to use the RS232 port or parrallel port. Has anyone
seen such a device and the software for it, i doubt it would be too hard to
build ?

Thanks in advance.
