'How to make ImageMagick do this kind of halftone (see image and description)?

Been looking at the halftone capabilites of ImageMagick. I've tried many combinations of -ordered-dither but without being near the result I want. I've tried Photoshop but that is not an option due to Linux platform and Licences and so on.

In Photoshop I get the result I want by making it Grayscale and then going through this line of choices: Image > Mode > Bitmap and Method Use: halftone screen with these parameters Frequency: 22 LPI Angle: 55 degrees Shape: Round

What would the convert command equivalent be for such outcome?

The original image

Photoshop halftone made by clicking Image > Mode > Bitmap and the choosing halftone screen with these parameters Frequency: 22 lpi Angle: 55 degrees Shape: round
