By use of this function block of the CAA_SerialCom.library a COM port can be opened and configured. The availability of ports depends on the hardware. The configuration of a serial interface is effected by the input pParameterList. The pointer pParameterList has to be assigned to an array of COM.PARAMETER comprising all configuration parameters required by the COM interface. udiListLength indicates the number of configuration parameters.
