How do I emulate a cmd/console screen?

I thought it'd be cool to make a retro computer terminal with green text and simulates an old computer screen similar to the Windows -CMD- or ms-DOS screen, how would I go about doing this?

Use a fitting font like Courier, Courier New, Raster Fonts or anything than looks like cmd. Then add a transparent textbox in the command prompt.

Do you want active commands, or no? If you want a handful of functional commands, you will have to reprogram all of those in your project.

1) Monospaced font (http://www.slant.co/topics/67/~what-are ... ming-fonts), can also use a spritefont, but all letters should inherit the same space (if retro is what you are going for, you probably want it to be pixelish, not smooth)

2) Black Screen background

3) Interpreter for commands if needed

4) Limit input to an arbitrary subset of characters if necessary

thanks guys for the input, I know what I gotta do now.
