Sure it's better have a winXP machine offline if you must use
proprietary software. I see many  Oxy-fuel welding and cutting machine
still working with W98! That's not so strange, believe me.
But again, the proprietary software of a control machine is made to
force the customer to stay with a particular company/brand. Because
updates are sold at astronomical prices. It's just a business. At the
end the instructions you find on CNC programs send via RS232 are
always the same: starting x, y coordinates  - intensity and type of
the shot/cut or other operation - move to the other x, y. This is
repeated until the end of file. It's not so simpe but it will gave you
an idea of what I'm talking about.

So there is a good possibility of migrating to linux, preferably with
the help of a specialist or a good community.
