No RS-232 headers, either, in a NUC, which I was secretly hoping for.

I did also look at the jitter info Oba-san has on his site referring
to EXTFSK64.  So USB -> RS-232 -> FSK radio port isn't the best way to
do this (even though it's done all the time).

So my next question is, how to the commercial USB interfaces that
support FSK actually do it?  Are they skipping the RS-232 part and
just wiggling (at 45.45 bauds) some wire that connects to the radio's
FSK port?
