I have written several daemons that listen to the serialport. Everything works well, however the serial port connections are actually USB connections over IP (using an USB network hub). This means the connection is lost once in a while which is detected and triggers the connectionLost method of the protocol. I tried numerous things to reconnect to the serial port but without success. When I reconnect to the serial port I doubt what to do with the reactor parameter, when I specify the current reactor, I am able to reconnect to the serial port, the connectionMade method of the protocol is triggered, but it will never trigger dataReceived although I know data is arriving. Does any body have a glue how you can reconnect to the serial port within a running reactor loop? -- Rene
