Added in API level 37

public List<SerialPort> getPorts ()

Enumerates serial ports.

Returns
`List<SerialPort>`	This value cannot be `null`.

Added in API level 37

public void registerSerialPortListener (Executor executor, 
                SerialPortListener listener)

Parameters
`executor`	`Executor`: This value cannot be `null`. Callback and listener events are dispatched through this `Executor`, providing an easy way to control which thread is used. To dispatch events through the main thread of your application, you can use `Context.getMainExecutor()`. Otherwise, provide an `Executor` that dispatches to an appropriate thread.
`listener`	`SerialPortListener`: This value cannot be `null`.

Throws
`IllegalStateException`	if this listener has already been registered.

Added in API level 37

public void unregisterSerialPortListener (SerialPortListener listener)

Unregister a listener that monitored serial port connections and disconnections.

Parameters
`listener`	`SerialPortListener`: This value cannot be `null`.
