I played with one tonight at a local museum. Had 4 lines on it.
He said UNIX machines, not FreeBSD specifically. He was talking about Android and iOS.
It works on all of them, including OSX.
OSX inherited SIGINFO from the BSDs, OpenBSD, FreeBSD, Dragonfly, and NetBSD all have it. Linux doesn't. I don't know why; but Google in the past has told me that patches to add it were rejected about 10 years ago.
