Yes. I made it flash 100ms-on-900ms-off for a ZERO, and 500ms-on-500ms-off for a ONE. There's a 1000ms-on-1000ms-off flash at the beginning to indicate the start point. And it's IPv4, so there's only 32 bits.

So it's slow enough to read out and type out into a text editor, then convert the typeout to its IP, but not slow enough that it's a bother.
