\class QextSerialPort
\version 0.70 (pre-alpha)
\author Wayne Roth

A cross-platform serial port class.
This class encapsulates a serial port on both POSIX and Windows systems.  The user will be 
notified of errors and possible portability conflicts at run-time by default - this behavior can 
be turned off by defining _TTY_NOWARN_ (to turn off all warnings) or _TTY_NOWARN_PORT_ (to turn 
off portability warnings) in the project.

\note
On Windows NT/2000/XP this class uses Win32 serial port functions by default.  The user may 
select POSIX behavior under NT, 2000, or XP ONLY by defining _TTY_POSIX_ in the project. I can 
make no guarantees as to the quality of POSIX support under NT/2000 however.

\fn QextSerialPort::QextSerialPort()
Default constructor.  Note that the naming convention used by a QextSerialPort constructed with 
this constructor will be determined by #defined constants, or lack thereof - the default behavior
is the same as _TTY_LINUX_.  Possible naming conventions and their associated constants are:

\verbatim

Constant         Used By         Naming Convention
----------       -------------   ------------------------
_TTY_WIN_        Windows         COM1, COM2
_TTY_IRIX_       SGI/IRIX        /dev/ttyf1, /dev/ttyf2
_TTY_HPUX_       HP-UX           /dev/tty1p0, /dev/tty2p0
_TTY_SUN_        SunOS/Solaris   /dev/ttya, /dev/ttyb
_TTY_DIGITAL_    Digital UNIX    /dev/tty01, /dev/tty02
_TTY_LINUX_      Linux           /dev/ttyS0, /dev/ttyS1
<none>           Linux           /dev/ttyS0, /dev/ttyS1
\endverbatim

The object will be associated with the first port in the system, e.g. COM1 on Windows systems. 
See the other constructors if you need to use a port other than the first.
