Device manager has no catagory for "ports-com & lpt"

My dell Inspiron laptop modem is not working. The Dell modem helper says that it is already in use and has a port confilct. When i go to the device manager there is not even a catagory listed for "ports". Under the modem properties is says that it connected to com 3.
