VGA 15 pin port data read and write using Matlab

I am using compaq presario cq40 laptop with windows seven ultimate(32-bit OS). I would like to access the 15 pin VGA port using Matlab (preferrably usi开发者_开发百科ng the Data Acquisition Toolbox). Do I require extra drivers or should download anything from Mathworks.com ??

I have already developed a program for sending digital signal through parallel port (LPT1) using digitalio() function in DAQ toolbox. I intend to use the VGA 15 pin port the same way (since there is no parallel port for the laptop).

Thank You.

It is not possible to access the individual pins on a VGA port.

The problem is that the graphics card completely abstracts it away(non-leakyish) so there is no way of working around it, not even at the kernel level.

I would not recommend using the VGA port as a data port anyway though.
