I also used 2Tone in the main Rttyrite windows and Winrtty Hardware
generated FSK. However, I used the Edgeport USB-Serial converter as I have
for a few years now. I've never had any issues with FSK or any other Serial
I/O functions. But, as Don alludes below, not all USB-Serial adapters work
with FSK and some other applications.
