Excellent!

Any chance you can run a similar test with a PL2303?  The FTDI SIO is only 
the second-most-likely converter to wind up in our device.  I see PL2303
breakout boards are available for < $10 on eBay, though you might have to work
a bit to find one that has pins for the handshake lines on the input side.
