We've done it a lot of different ways.  The top 2 that I would recommend
are:

1) Use JAVA
2) Use cURL
3) Use Reflection VBA

Lars Appel created an excellent example of JAVA use
http://www.editcorp.com/Personal/Lars_Appel/JavaDemo/telnet/.  We've
actually gone beyond that example and we now use JAVA to control HP 3000
programs in a number of different ways.  For example, we do a store to disc
and then retrieve the store to disk and move the backup to a PC network and
then to DVD's for off-site storage.  We also logon to the HP 3000, extract
the IMAGE schema and data from and IMAGE database and then move the results
to a target machine (UNIX, Windows, Linux, iSeries) and use scripts to build
the replacement RDBMS.  We have several other uses as well. If you have JAVA
skills, I would recommend this approach.

The cURL http://curl.haxx.se/ approach is perhaps simpler in some ways in
that they do not require the installation of so much software.  However, you
will have to use the debug output to get it right.  If I recall the problem
correctly, the HP3000 emits an extra "CR" that the cURL client does not get
from UNIX machines, therefore, you will need to allow for that.  Moreover,
the use of TELNET and cURL are not common, therefore, it is difficult to
find examples of how to do it.

The third case, Reflection VBA, is an approach that we first used a few
years ago.  It is actually very easy to do and works extremely well.  I
provide a fairly detailed explaination, albet with an older version of
Reflection,  at our website http://www.xformix.com/vbexample/index.html.
What you is create a macro with Reflection that is actually a Visual BASIC
program.  We actually then turn around and use Visual BASIC instead of the
builtin VBA to drive the application.  We have also used C++ do do this as
well.  Reflection provides an ActiveX (COM) client that you can use for this
purpose.

Naturally, you can use any programming language you like to do this.  The
biggest problem that I have found is that by simply using a programming
language instead of a library that is designed for dialog with a host the
program is more likely go get hopelessly lost when something goes wrong.
The three methods I have suggested above all use a library that is designed
to do things like wait for a certain kind of response from the host, time
out, etc.  Therefore, you can create a good quality reliable client without
a lot of work on your part.

Hope this helps.
