I have successfully built this data-cable: **broken link removed**
The MAX232 seems to be a handy device.
Now, I want to build a serial cable on/off switch for my laser-pointer based on the MBUS-cable-diagram.
How do I wire the MAX232, so I can send a command by the pc that turns the laser on or off, ie. continuos 3v or 0v are supplied ?
What are the settings and commands on the pc side ?
I want to write a little C-program.
