The basis of EMC is NOT the C language, it is real-time extensions to
the Linux kernel. In DOS, people roll their own, take over the interrupt
system,
and grab control at the hardware level. This is not very portable, as it will
work on brand "A" motherboard, but not on brand "B". But, lots of people
do it. If the CNC program is the ONLY thing you will run, then it may be
reliable, but may be interfered with or interfere with various devices, device
drivers, etc.

The advantage of Linux is that you can send G-code files over a network,
edit G-code while another program is running, pop up a calculator while
entering some MDI commands, etc.

And, of course, there's DesknCRT, but you lose all of the above, as it
doesn't run under Windows, or didn't until recently, anyway.
