[oe] UART keyboard as /dev/input?

[Adam Lee]

How can I get a UART keyboard to show up in `/dev/input/`? I believe
`inputattach` was the tool that was favored until some years ago, but it
appears that it no longer is being used in modern Linux systems. I can't
seem to find the replacement for it, however.

Apologies if this question isn't suitable for this list. Feel free to
suggest me another list.
