This chapter has described two different but related techniques for connecting to other computers, devices, and networks. TAPI, the Telephone API, can be used to make and monitor connections to devices, and then the application can obtain a suitable media handle for transferring data using data, voice, or other protocols. RAS, the Remote Access Services, allows connections to be made to Windows NT or 2000 servers, and for a Point to Point Protocol (PPP) session to be created. Once the connection is established, an application can use TCP/IP to communicate with the server.
