You don't want this one if you might need to send a break. Most I've seen are uplcom (good support in most OS, you'll find some if you search title&description on ebay for PL2303 or PL-2303) or uark (I've seen both uark and uplcom in the same packaging - translucent blue ends, transparent cable coating - you can't tell much from appearance).
