It shares at least 90% of the rtl with the other BSD's, so it isn't  
that different at the basic unix level. It's mainly different if you  
want to use OS X-specific functionality (like its gui environment  
instead of X11). Regarding serial port stuff: none of the Macs which  
can run the latest version of Mac OS X still has a serial port. There  
are USB-serial converters out there though, and their drivers (.e.g  
from Keyspan) create a regular serial port device in /dev which works  
identically to those under other unixes.

It's not because other interfaces are available, that there is no  
compatibility with the traditional unix way of working.
