The closest so-far appears to be Kermit. It's been around since CP/M, but apparently there's still no centralised language reference and the syntax predates Perl.

Uh email? It’s not exactly exciting but there are loads of tools available for automating emails. Definitely asynchronous. Does it fit your needs?

No, it needs to be serial communication. My use case is talking to a CNC.

Edit: fat fingers: "ea" -> "to a"

I used expect a lifetime ago to reliably talk to a bunch of very strange ISDN modems.

I think something like expect also exists for more modern languages, but tcl is still easy enough to learn (just a little unusual, everything is a string)

That's several recommendations for expect. I'll start digging. Thank you.
