Before UNIX was ported to the PC, I used a DOS program called Crosstalk Communicator.

Today it's so easy to run a small UNIX kernel on a PC.

Why would "industrial control areas" still be using Windows, if what they need is terminal emulation? Tradition? Windows-only software?

Windows on a networked computer sounds like a potential security hazard in such places.

Maybe they can get the domain name through UDRP.

32 bit windows XP was an RTOS. This is one of the reasons so many people where reluctant to leave it.

Windows CE can be a RTOS. XP is not.

"Is Windows XP Embedded a real-time OS? Windows XP Embedded satisfies the vast majority of performance requirements. However, if you require a more powerful real-time support for your Windows XP Embedded OS, you can utilize one of the real-time extensions that are available through third-party vendors."

There are apparently third-party real-time extensions available, but if that counts then the existence of CONFIG_PREEMPT_RT makes Linux a RTOS and I think that'd be a pretty silly claim too.
