[bitserf]

Have you tried Iosevka (the Slab variant is serif)?

Not a bitmap font, but pretty customisable. With hints of PragmataPro, it's my go-to font at the moment. Looks especially nice with OS X font hinting.

My command-line for building is:

$ make STYLE_COMMON='v-tilde-low v-asterisk-low v-underscore-low'

This gives the vertically centered asterisk and tilde, and puts the underscore below the baseline.
