I recently (last week) wrote a simple socket listening program that runs on
Linux. It's multi threaded and supporting multiple simultaneous clients, and
performs SSL encryption on the data. It didn't take very long, I wrote it in
python using examples from the python documentation (www.python.org) as well
as the examples included with pyopenssl (pyopenssl.sourceforge.net). My
listener provides 2 way asynchronous communication but it sounds like yours
is much simpler that that. You just need to write a program that has Oracle
ODBC will listen for requests from the HP.

I also wrote my client in python so that won't help you at all much on the
HP3000 side but you should be able to write a client in any language that
supports sockets.
