This integration prevents a situation in which aborting a SerialPort's WritableStream can be blocked on waiting for a partially-written chunk of data to be written to the port. If the port is waiting for the peer device to provide a flow control signal it could be blocked indefinitely. The intent of aborting a WritableStream is to immediately stop trying to write data to the underlying sink. The introduction of an AbortSignal to the controller was done to fix bugs like this.
