</b><dd>Wayne Roth</dl>A cross-platform serial port class. This class encapsulates the POSIX portion of <a class="el" href="classQextSerialPort.html">QextSerialPort</a>. 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. <p><hr><h2>Constructor & Destructor Documentation</h2><a name="a0" doxytag="Posix_QextSerialPort::Posix_QextSerialPort"></a><p><table width="100%" cellpadding="2" cellspacing="0" border="0"> <tr> <td class="md"> <table cellpadding="0" cellspacing="0" border="0"> <tr> <td class="md" nowrap valign="top"> Posix_QextSerialPort::Posix_QextSerialPort </td> <td class="md" valign="top">( </td> <td class="mdname1" valign="top" nowrap> </td> <td class="md" valign="top">) </td> <td class="md" nowrap></td> </tr> </table> </td> </tr></table><table cellspacing=5 cellpadding=0 border=0> <tr> <td> </td> <td><p>Default constructor.
