Depends on the API you are using. I assume you are asking about blocking IO.

A process using accept() blocks on the call to read from the socket, and
the kernel does not schedule the process to run until the blocking call
completes.

So the usage of "waiting on" is imprecise, because it implies that the
process controls scheduling, which it does not.
