FOR IMMEDIATE RELEASE

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.
