You need to have a parallel interface card before you can send codes to  Neuroscan, DMDX refers to them as PIO cards.  Assuming you're using  hardware that someone else has setup you would use the  keyword,  around here 8 communication lines are run to the Neuroscan machines  allowing codes from 0 to 255.  There's documentation in  TimeDX on setting  up PIO.                                                 /"\\   -jonathan (j.c.f.)                            \\ /                                                  X      ASCII RIBBON CAMPAIGN - AGAINST HTML MAIL  / \\    To be, or not to be, those are the parameters.
