ImageMagick resize without interpolation

I have a small pixel map and want to resize it for better readability.

Using mogrify -resize 1600% I get an interpolated image: .

What I'm trying to get is this: .

Can this be done by ImageMagick or any other open source command line tool?

I finally found the solution: using -scale instead of -resize does the trick. It is 'hidden' under the heading Scale - Minify with pixel averaging, therefore I overlooked it at first, searching for magnification instead of minification.
