I have a piece of hardware that needs to be controlled with software, some screen scraping and about 5 to 10 commands need to be executed. I am flexible with language and platform but ideally I would like it to run on Linux for stability purposes. I would if possible like it client / server type set up but that can be developed later. I have done initial research and have determined the connection speeds, and the polynomial check sum.

I have written many pieces of software for controlling machinery using RS232 and RS485. When you mention connection speed and polynomial check-sum I presume you have the full details of the communications protocol used. If that is so then I would be happy to build this system for you.

I am very interested in this project -- it sounds quite interesting, and well within my abilities, as someone who does embedded systems development for a living :-). I have send a more detailed proposal as a private message -- but in short, I propose a lean, Linux-based (well, anything *nix) solution written in C, with a client-server model.
