'Return a list of associations involving this object, optionally
limited by the result class (the name of the association class).
NB Associations are treated specially; although WMI only returns
the string corresponding to the instance of each associated object,
this module will automatically convert that to the object itself::
c =  wmi.WMI ()
sp = c.Win32_SerialPort ()[0]
for i in sp.references ():
print i
for i in sp.references (wmi_class="Win32_SerialPortSetting"):
print i'

    except pywintypes.com_error:
        handle_com_error()
