create
fun create(portName: String, baudRate: Int = DEFAULT_BAUD_RATE, callback: RadioTransportCallback, scope: CoroutineScope, dispatchers: CoroutineDispatchers): SerialTransport(source)
Creates a side-effect-free SerialTransport. The owning transport service invokes SerialTransport.start after it has published session ownership, so even immediate serial callbacks carry the correct generation.
