I must respectfully disagree with you Darryl. I've been using and
selling the FTDI Chip USB to Serial Converter for several months now
because it works great with every soaring flight recorder I've tried it
with.

I use FTDI converters too with success. In fact there are two main
USB-serial chipsets available: FTDI and Prolific. Prolific does the good
work too, provided that.. you have a real one. Market (at least
European) is literally flooded with cheap counterfeits from China, which
make a lot of transmission errors.

Anyway both chipsets are ok with current drivers and proper settings.
