A value `< 0` for `byte_timeout_ms` means no timeout. A value `< 0` for `byte_timeout_ms` means infinite timeout.
With a value `== 0` for `byte_timeout_ms`, the method should read/write once in a non-blocking fashion and return
immediately.
Their return value should be the number of bytes actually read/written, or `< 0` in case of error. Their return value should be the number of bytes actually read/written, or `< 0` in case of error.
