Bestselling Serial Cables Reviews:

Great USB-to-Serial for console connections

“ But I've used several USB-to-Serial cables before; this does what the rest of them do, save that the braided cord construction and led activity are nice to have, and as with Prolific's previous interfaces, this will work on just about anything w/o the need for drivers. ”
