I’m surprised there is no mention of netcat (nc).

Yes

    nc -vz host port

is my go-to.

and, the -u option lets you send and receive UDP!

Netcat got replaced by socat, right?

I use socat for serial-line things (like simulating a serial port for unit testing). I didn't occur to me that it can be a netcat replacement.

There is near the bottom

Oops, so there is!
