I am trying to control a HT23-400 stepper motor through LabView using a MCS9835 parallel port and a 3540M motor drive through a 32 bit windows vista . I have a few sample programs that should work or at least send some signals, but it seems that the PCI parallel port is not sending any information to the motor drive.
Can you give me any information about how can i make the whole system work?
thank you for your help.

Take a look at this thread, it should help:

Hi Gant88,
To use VISA with a parallel port, ensure that you pull down pins 11 and 12 to ground.
Check out this KB on using hte parallel port: http://digital.ni.com/public.nsf/allkb/B937AC4D8664E37886257206000551CB?OpenDocument. Method 1 outlines what I just said.

Hi Gant88,
The program that you had posted is fairly simple and straight forward. Double check that the I/O port address is correct and check that the values that you are sending are valid (the list of command values should have been included with your drive). Below are a few articles about communicating with parallel ports using LabVIEW. If it still does not work, you may need to contact Moschip for more information about how to communicate with their drive.
