I read that when the serial port encounters an error (frame error or so, I imagine?) it stop receiving data until the library function "getCommError()" is called.
Troels: I think you are right Am I on the good track? Can I call this function from my pyserial code? Why pyserial does'nt raise a serial.SerialException in this case? Troels: Well , you have the source, don't you ? The serial lib has a handle somwhere. Call getCommError with that ? Or ? tpt -- http://mail.python.org/mailman/listinfo/python-list
