TCP Server Deux v1.0.0 Released by Deep Sky Technologies, Inc.

Full Release of Popular Server Component

Vero Beach, FL - Friday, March 22nd, 2002: Deep Sky Technologies, Inc., today announced the full release of TCP Server Deux for Macintosh and Windows. TCP Server Deux is a 4th Dimension component which provides a cross-platform, flexible TCP level server. TCP Server Deux allows 4D developers to run one or more higher level protocol servers in a single 4D database without have to code for multiple listeners, threading, messaging, or many of the other functional elements that often complicate custom servers in 4th Dimension.

With TCP Server Deux, a 4th Dimension developer can easily develop a server available through multiple protocols. For instance, having a Domain Name Server with an integrated web interface is a simple matter; the same is true of an email server, available through both SMTP and POP3, with a HTTP interface over a custom port for administering the settings and accounts in the email server. TCP Server Deux handles all of the listeners, threading, multiple processes, and communications necessary in a custom server written in 4D. By handling all of these issues as a TCP server, and with suitable hooks available for processing of requests and setting responses, it is then a simple matter to merely write parsers for higher level protocols that reside on the TCP layer.

"TCP Server Deux providers a powerfully flexible yet simple TCP level server for the 4th Dimension developer community", said Steven G. Willis, President, Deep Sky Technologies, Inc. "With TCPsd, 4D developers now have the flexibility to incorporate multiple, higher level protocol servers into 4D with much less effort than previously required. All of the threading, process handling, and listener management is handled in the TCPsd component. This provides a solid basis for us to provide higher level protocol servers with minimal effort to the 4D developer community."

TCP Server Deux includes a comprehensive diagnostic time logger to aid 4th Dimension developers identify the response times of incremental functional units within their 4D based applications.

TCP Server Deux works with other components already available from Deep Sky Technologies, Inc. The TCP Deux component is used for all TCP level access within the TCP Server Deux component. And, of course, the BASh component is used by TCP Server Deux for a lot of the basic functionality available within the server component.

TCP Server Deux does require a robust TCP plugin for access to the TCP communication layer from within 4th Dimension. Though TCP Deux does provide compatibility with 4D Internet Commands, unfortunately 4D IC does not provide a robust, and asynchronous, TCP listener routine. Because of this, TCP Server Deux only works with Internet ToolKit (ITK) v2.0.x and v2.5.x. If used with ITK v2.5.x in conjunction with an ITK SSL Server license, full access to the SSL layer is available for all functionality within TCP Server Deux.

A fully functional demo mode is also available. Demo mode allows for the component to be fully used for 30 minutes when no serial code is supplied to the TCP Server Deux component.

TCP Server Deux is fully compatible with 4D v6.8.x. Separate component archives are provided for use under 4D v6.7.x or 4D v6.8.x. All calls and functions operate exactly the same under both releases of 4D, allowing for seemless upgrades to the latest version of the 4th Dimension development environment.

A full manual, explaining every call and feature available in TCP Server Deux, is included with the component.

Features in the TCP Server Deux component

The functionality available in the TCP Server Deux component includes:

  • Full support for multiple protocols services;
  • Server management for any combinatins of ports and IP address;
  • Settable server throttle greater sharing of CPU;
  • Full internal management of TCP listeners;
  • Internal management of 4D process for maximum performance;
  • Dynamic creation of server services;
  • Procedural starting and stopping of all server functionality;
  • Compatibility of SSL layer when using ITK v2.5.x or above;
  • Customizable hooks for processing requests;
  • Compatibility with 4D v6.7.x or above, including 4D v6.8.x;
  • Full support for MacOS 8/9, MacOS X, and Windows 98/2000/NT/XP.

TCP Server Deux Professional Also Available

TCP Server Deux Professional is the source code version of the internationally popular TCP Server Deux 4D component. By licensing TCP Server Deux Pro, the actual source code for the TCP Server Deux component is made available to the licensee/developer.

TCP Server Deux Professional is geared towards companies that want to leverage their access to source for all of their systems. It provides the ultimate in protection for using 4th Dimension components available from Deep Sky Tech., Inc. By licensing TCP Server Deux Pro, a company has full access to the source code used for every release of the TCP Server Deux component.

TCP Server Deux Professional is also ideal for 4D programmers looking to expand their expertise in the 4D language. The concepts and organizational structure of the TCP Server Deux Professional source code is a wonderful learning tool for expanding the development skills on any 4th Dimension programmer. Just as TCP Server Deux has become a basis for developing and deploying TCP server based applications with 4D, TCP Server Deux Professional is a solid basis for expanding the horizons of 4D developers of all levels of experience.
