Vena,
You may want to try Valuemotion 2.0, which was supported under Windows 3.1, you may want to give it a try from DOS since Win 3.1 runs just as a graphical program in DOS. We don't have a specific DOS driver available, so this one should be the closest one.
For finding this driver go to www.ni.com, then click on your left on "download software", then "drivers and updates", then "all software versions", then "motion control", then "windows 3.1", then "driver".
Or click on the following link:

Read the TEXT files for installation instructions.
If you would like to ask more detail questions please give us a call to dis
