FOR IMMEDIATE RELEASE

Deep Sky Technologies, Inc., Announces Release of TCP Deux v1.0.0

Full Release of New 4th Dimension Component

Vero Beach, FL - Thursday, July 26th, 2001: Deep Sky Technologies, Inc.,
today announced the full release of TCP Deux v1.0.0 for Macintosh and
Windows. TCP Deux is a 4th Dimension component which provides
cross-platform TCP wrappers for different TCP plugins available for 4th
Dimension. The plugins supported within TCP Deux include 4D Internet
Commands v6.7.x, Internet ToolKit v2.0.x, and Internet ToolKit v2.5.x.

With the TCP Deux component, a 4th Dimension developer can code TCP level
routines without worrying about which particular plugin is going to be
used. TCP Deux provides a very simple upgrade path for developers to write
one set of code. With TCP Deux, a 4D developer can begin by using the free
4D Internet Commands for all TCP communications and upgrade to the
commercial Internet ToolKit plugin when the needs arises, all without
changing a single line of code.

""""""""TCP Deux is the foundation for our growing line of 4D components"""""""", said
Steven G. Willis, President of Deep Sky Technologies, Inc. """"""""With TCP Deux
in place, our components for higher level protocols allow developers to
more easily implement essential functionality in all of their 4D projects.
TCP Deux is the basis for us to provide a comprehensive solution to
difficult protocol issues that many 4D developers regularly experience.""""""""

Separate 4D components for higher level TCP protocols are or soon will be
available from Deep Sky Technologies, Inc. Common TCP protocols currently
available include SMTP, POP3, FTP client, HTTP/HTTPS client, and many more.
A full manual, explaining every call and feature available in TCP Deux, is
included with the component.

Features in the TCP Deux component

TCP Deux provides cross-platform, plugin independent routines for
handling all TCP communications in 4D. The functionality available in
the TCP Deux component include:

- Stream and listener openers and closers;
- Stream status checking, individually or for all open streams;
- Processor friendly stream status waiting routines;
- Full support for sending and receiving text and binary data;
- Full support for sending and receiving directly from documents;
- Full management system for TCP communication streams;
- Full multiple 4D process (handler) support for TCP servers;
- Accessor methods for updating and extracting stream information;
- Accessor methods detailing TCP environment on local machine;
- Transparent support for IC v6.7.x, ITK v2.0.x, and ITK v2.5.x;
- Full SSL support when using ITK v2.5.x.

The TCP stream management system, entitled TCPd Streams Stack, built into
TCP Deux provides a complete management and tracking system for 4D
developers to use for handling all TCP streams. The TCPd Streams Stack
provides transparent management of all TCP streams, allowing the 4D
developer to concentrate on management the higher level TCP protocol being
coded for instead of the direct management of the TCP connection streams.
And, the TCPd Streams Stack even provides full support for common TCP
serving options (e.g. distributed process handlers within 4D).

The TCP Deux component requires the BASh component be installed to operate
properly. BASh is available for free from Deep Sky Technologies, Inc., and
provides essential routines needed by all 4D programmers.

Developers Everywhere Are Talking

""""""""We are very happy to see the addition of another component product to the
4D product community. TCP Deux is an exciting new product that will provide
4D Developers with valuable functionality to add to their applications
through the simplicity of components.""""""""

""""""""If you need to do anything involving ITK or Internet Commands, TCP
Deux will save you hours of reading, coding and testing. Used in
conjunction with its sister components, HTTP Client Deux, SMTP Deux,
etc., it makes the use of these technologies a breeze.""""""""

""""""""Recently I needed to add Web client features to a project and I
decided to try out TCP Deux and the free HTTP Client Deux components.
With these components I was able to add the basic web page retrieval
functionality I needed in about fifteen minutes. These tools should
be particularly appealing to developers who do not already have a
detailed understanding of TCP/IP or higher-level protocols like HTTP.
Virtually all of the underlying details are built into the components
and work automatically. I highly recommend the TCP Deux family of
components to every 4D developer.""""""""

""""""""It is nice to see a feature rich and well implemented foundation for
4D developers to work with for all of their online needs. I am
looking forward to future protocol support building on TCP Deux,
especially any servers that may become available.""""""""
