The examples I found are mouse.py and gpsfix.py and there only listening on the serial line. It seems that with twisted I have some sort of a thread running which will trigger some methods (e.g. dataRecieved) as it reads something from the serial line.

I'm mot sure if this asynchronous approach is what I need, because the protocol I'm implementing is strict Master-Slave. - Markus -- __________________________________________________________________ IMKO Micromodultechnik GmbH Markus Hubig System Administration & Development Im Stoeck 2 D-76275 Ettlingen / GERMANY HR: HRB 360936 Amtsgericht Mannheim President: Dipl.-Ing.
