SSI_ACT windows environment variable

I know this variable controls the timing of the parallel port, but I couldn't find any detailed description of the parameters (eg. 250,250,250). Any clues ?

Did you try MSDN or Technet? Old Windows API or Serial/Parallel port programming faqs online also help.

There is a lot of parallel port info at www.lvr.com
