anyone tried opening the magic file "con" from MS DOS Edit?

I was hoping for an editor but it turns out instead it happily opens it but then hangs forever

@foone What if you push ^Z so it knows it finished loading CON?
@fozztexx I tried, no change
@foone ^Z followed by ^M like I have to do with `COPY CON FILE.TXT`?
@fozztexx Nothin'
