Sharing Modem Connected to server

Hi Friends, I have a LAN with SUSE 8.2-Samba at server and about 10 Windows Nodes connected to it. The server has a modem attached to it. The Server is acting as PDC & Database Server. Delphi application is Running on Nodes and depending on User input that application need to establish dial-up connection with similar setup at different locations. The Dial up Telephone Number, User ID, Password are user inputs at Delphi application. Can Delphi application Dynamically accept these parameters and using Centrally attached modem Connect to respective site ? If yes how can I do that Thanks Best Regards R. S. Patil
