getPortsWithFullMessages static method

List<PortInfo> getPortsWithFullMessages({ String classGUIDStr = GUID_DEVINTERFACE_COMPORT, })

Using getPortsWithFullMessages to get Serial Ports Info Parameter: {String classGUIDStr = GUID_DEVINTERFACE_COMPORT}, refer to https://learn.microsoft.com/en-us/windows-hardware/drivers/install/guid-devinterface-comport You can set classGUIDStr = GUID_DEVINTERFACE_USB_DEVICE return PortInfo({ required this.portName, required this.friendlyName, required this.hardwareID, });
