FYI, if you have an FTDI USB/Serial dongle you can use the FTDI FT-Prog utility to reprogram the chip to invert polarity from normal. I did that with my 'Arduino' USB/TTL cable in order to talk to an Rb osc. No need to mess around with additional inverters. You can get the utility from the support area of their website.
