Recompilation using libwine is not feasible as our code is quite MSVC specific,
also including some assembly language. We should also consider MFC
recompilation legality. Simply Linux/Mac userbase is so small that we cannot
spend time on this.

On the other hand, modifying single class that does serial port enumeration and
communication is VERY simple.

I understand we can make "serial driver DLL" and very simple .dll.so  that
would do the same job on Unix/Wine, however this is not very practical as we
would have to maintain library dependencies, develop different versions (one
for BSD, one for Linux, one for Mac). On the other hand detecting host OS type
is fairly simple by trying to dlopen a few libraries/functions (if they fail we
can always fallback to Windows serial ports and trust Wine it is completely
supported like it is now on Linux). It is all POSIX, so Unix part would be
simply just a simple library with a few system dependent tweaks.

It would also make bluetooth connection possible, which is AFAIK totally
impossible with wine (We would simply let user connect rfcomm device from the
host system and then use it using open()/read()/write()/select() acquired from
wine_dlopen).
