set RTL on close

hallo everybody, I'm using a Boarduino with a FTDI cable, but I'd need to "set RTL on close" in the "USB port settings" options (see for details).

But I cannot find the sub-entry "USB" in my Device Manager->Ports entry :( : I have another entry, called Universal Serial Bus Controllers, with these sub-entries: "USB root hub" and "PCI to USB Open Host Controller", in which I cannot set the "Port Settings".. What should I do?

Hoping all this was clear, Please help me! Ale

Probably means you don't have drivers installed. Do you get a high com port number 4-10 showing up in Arduino under tools menu?
