Catalyst SocketWrench (16-bit) is a set of ActiveX controls that simplifies Windows Sockets programming. This package consists of a Windows Sockets control, as well as a Remote Access Services dialer control. The Sockets control gives you all of the functionality you need to write both client and server applications using the TCP or UDP protocols. The RAS dialer control can be used to manage Dial-Up Networking sessions directly from within your application. Instead of depending on the autodial feature, you can take direct control of the session. This includes determining if a Dial-Up Networking session is already active, and monitoring the connection status.
