Hi, Well, so far it seems to work ... The signal handler gets "called" by another application which in turn will stuff info in my sys.stdin, I need then to "raw_input" the info and put it in some type of data structure in a safe way so my main loop can then reader/pop it. ref: (ps: I'm trying to setup a Python high level interface for my kids to learn the language / be interested) http://realtimebattle.sourceforge.net/ Regards, hg -- http://mail.python.org/mailman/listinfo/python-list
