Thanks Paul,
I did that and didn't work. I could ignore the data that I am
receiving, because I could blindly send the characters that I need,
but it doesn't seems to receive it. The strange thing is that
from the command line works!!, but when I call the function from
any application with exactly the same parameters as I do from
the command line it does not. I tried to use "Procomm Plus" and it worked fine,
I think I am going that way, I was hoping to do this in
native FoxPro, but you have to do what you have to do to make things
work.

Thanks to you all for your help.
