\author Stefan Sander
 
A cross-platform serial port class.
This class encapsulates the POSIX portion of QextSerialPort. 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 that _TTY_NOWARN_ will also turn off portability warnings.

\fn Posix_QextSerialPort::Posix_QextSerialPort()
Default constructor. Note that the name of the device 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_FREEBSD_ FreeBSD /dev/ttyd0, /dev/ttyd1
_TTY_LINUX_ Linux /dev/ttyS0, /dev/ttyS1
<none> Linux /dev/ttyS0, /dev/ttyS1
\endverbatim
 
This constructor assigns the device name to the name of the first port on the specified system.
See the other constructors if you need to open a different port.

\fn ulong Win_QextSerialPort::lineStatus(void)
returns the line status as stored by the port function. This function will retrieve the states
of the following lines: DCD, CTS, DSR, and RI. On POSIX systems, the following additional lines
can be monitored: DTR, RTS, Secondary TXD, and Secondary RXD. The value returned is an unsigned
long with specific bits indicating which lines are high. The following constants should be used
to examine the states of individual lines:
 
\verbatim
Mask Line
------ ----
LS_CTS CTS
LS_DSR DSR
LS_DCD DCD
LS_RI RI
\endverbatim
 
This function will return 0 if the port associated with the class is not currently open.
