Hello, I configure the serial connection using:
self.port = serial.Serial(baudrate=57600, timeout=0.06, parity=serial.PARITY_EVEN, stopbits=serial.STOPBITS_TWO, bytesize = serial.EIGHTBITS) After X hours of inactivity I loose connection to my serial device, with error message "Input/Output error" printed to stdout. The error happens both on Linux and Windows (although the error message is probably different on Windows, I've only been told the behaviour is the same). I cannot find an obvious reason for why this is happening, and since it happens after a long time of inactivite, debugging is awkward. So I though I'd run the question through the expert panel for ideas, before venturing down the path of pain and suffering myself :) Best regards, Frank -- http://mail.python.org/mailman/listinfo/python-list
