Does parallax specifically recommend the keyspan converter? (I couldn't tell rbayer's post).
I've just been doing some research on USB to serial converters, and it seems that many people can't get the keyspan ones to work with anything, and thier support is non existant.
For programming another microprocessor that I work with, a cable from FTDI is the only one that works, in the version that doesn't specifically support a usb to serial converter (IE it is the only one that is able to do a good enough job fooling the software). Most other ones work in later versions of the software, except Keyspan. The only place that I have been able to find the serial converter to buy online is

Hope this helps, and let us know what you find that works.
