Actually, it's RS274 that's different for every manufacturer. RS274-NGC 
was an effort by NIST to clear up all the incompatibilities by saying, 
"look, here's how it should work, dammit" and EMC was the reference 
implementation that came out of that. So, RS274-NGC is only one specific 
dialect. But it's the right one :)
