All Iam looking forward for is a simple example, I
have the code in VC++. Iam pasting it below.
I want it to run on CGI through perl and have
interfacing from a browser.
This is just to test whether we r able to.
We r in process to test whether a new project on RT
control of Hardware is feasible.
Anyone help.
Mukund have alook at this and tell me how do u go
about it.
Iam also putting the pin configuration on.
I plan to paste it on programmers list as well but
that list is not so active.
We use a PCL card.

vicki
