Ok, I am getting it. Just played around with the output pins using a LED. The signal goes from -11.6v to +11.6v. Inorder to get a TTL signal, it seems we need to use a voltage converter MAX-232(source:- codeguru forums). Do you know any other way to produce a TTL type signal (0-5v) other than using that converter? I am not sure we can produce without using that, but in case if have any idea lemme know.

Thanks for the info,
-P.
