David, This sounds like a job for a terminal server (RS232 over IP). They are very common and easy to work with. In fact, I'll be on your campus for the next 2 weeks (flying in Sunday) to help install an accelerator that is being moved. Part of the installation includes such a device. I'd be happy to meet up and show it to you along with code. Our control system software is written so that you can open a direct device (serial) connection or a TCP/IP connection with a simple command line argument. This results in minimal code changes. If you are interested in meeting or want more detailed information, we can take it off-list. My contact at Vanderbilt is Mike McCurdy, 410 24th Ave S.
