Set DOS console mode (40 character mode)

Question

How exactly would you set the DOS console to 40 character mode (which I belive looks like this: http://www.youtube.com/watch?v=_ZIzCGir58Y)? I know you can do it, as in old games like ZZT.

Answer 1

In real MS-DOS, you could use MODE. It might also work in Windows 3.x or 98's "MS-DOS Prompt".

mode con cols=40

However, you cannot do the same in Windows NT. Aside from the fact that Windows NT "Command Prompt" is not DOS, it just does not support 40 column full-screen text mode anymore.
