Thanks your your reply Eric.
I just did it.
Now, my app is ready to use, but I got the follow problem.
Let me explain you:
I´m use two pc in one of the is the app the other one none, both has Win98, faxmoden and networkdrive working ok.
The proble is when I order to RASCONTROL (by Ulseth Software) conect with the other pc, it return me a error message "The machine that your are calling not respon, in this time, try later"
When I call to the user that be in the other pc, he toll me that the phone was ringing but anythingmatter.
The question is How can I put the OS to be pending for incoming calls, I need other software or just some configuration.
Please help me to resolve this problem.
