I'd like to run the application with twistd. But it looks as if SerialPort does not really fit into this framework. It does not implement IService, so `my_serial_port.setServiceParent(collection)` does not work.
Just implement your own service - subclass t.a.s.Service, write your own startService and stopService methods that start and stop the serial port.
Is there any technical reason that SerialPort does not implement IService?
The TCP port doesn't implement IService either... A service is supposed to be something you can start and stop, and encapsulates a self-contained piece of business logic. The purpose is both deployment and ease of regression testing. So maybe your service starts both a webserver and a serialport, because it requires both -- which is why mostly you should just implement your own service classes. -Itamar
