Hello, I'm writing software to interact with Diabetic Blood Sugar Meters. So far I've got 2 working and am trying a third. Most meters use a USB to Serial cable and I need to identify the COM port it is using. For the two I have working this was easy using the following script: ; Set return varialbe to -1 for error $return = -1 ; Flags for WMI $wbemFlagReturnImmediately = 0x10 ;DO NOT CHANGE $wbemFlagForwardOnly = 0x20 ;DO NOT CHANGE ; Try to connect to WMI $wbemService = ObjG
