Were you testing it on a Virtual Machine or on a real hardware?

That is weird, here I get a dos prompt and can use DOS in the new resolution :/

Hello! Just tested it.
It changes the resolution, but now I just don't see anything. I tried doing Ctrl+C exiting it but to no avail :(
Any reason why could this happen?

Try this as an example http://www.edzup.co.uk/images/EVGAMODE.zip
 
Usage: EVGAMODE [mode]
 
where mode is either 640x480, 800x600 or 1024x768. If you use CLS it will return to the previous resolution as the mode is just a temporary change :).

Technically it would put the screen into a VGA/SVGA resolutions so text output would be in that resolution till you used CLS when it would return back to the original resolution.
 
There is also high Res text mode.
