Issue or Suggestion Description

I am tracking down some tricky issues around serial port management in the face of the ESP32 continually rebooting. That situation tends to cause buffer overruns that make it hard to maintain a coherent serial reader state.

I am confused by this line of code and a few similar ones: const { value: p } = await this.transport.read(timeout).next(); . this.transport.read(timeout) creates a new instance of a generator function, then .next() waits for the function to yield. That generator function is never used again. Every use of .next() is in the context of a new generator function instance, so what is the point of using a generator that only generates one value? Isn't that effectively the same as an ordinary function, but with added complexity?

There is a similar situation with readLoop() in newRead().

I am not a JavaScript expert so I could be missing something. Please help me understand the rationale.
