The attached patch replaces CTB with native calls on Win32 and *nix
systems (ie: Linux, OS X, FreeBSD, etc).
It also contains a small tweak to the CMakeLists file to allow searching
for portaudio in the default place that FreeBSD places it. Since
portaudio 1.7 and portaudio 2 can coexist, FreeBSD places it in
/usr/local/(lib|include)/portaudio2. The included change allows
locating it there as a hint.
I haven't actually tested the Win32 code yet since I currently don't
have a Windows box set up with a serial connection to something I can
test. If nobody else tests it first, I'll likely drag out a break-out
box and test it this weekend using a multimeter or something.
