= About QextSerialPort =
QextSerialPort provides an interface to old fashioned serial ports for Qt-based applications. It currently supports Mac OS X, Windows, Linux, FreeBSD.

== How to use (1) ==
 * Download the source code.
 * Put the source code in any directory you like. For example, 3rdparty:
            |-- project.pro
            |-- ....
            |-- 3rdparty\
            |     |-- qextserialport\
            |     |
 * Add following line to your qmake project file:
            include(3rdparty/qextserialport/src/qextserialport.pri)
 * Using QextSerialPort in your code. Enjoy it!
            #include "qextserialport.h"
            ....
            QextSerialPort * port = new QextSerialPort();
            ....
            
== How to use (2) ==
It's very easy to compile QextSerialPort directly into your application
(see above section), however, we would prefer to use it as a static or
 shared library.
 * Download the source code, and put it in any location you like.
           |-- yourpath\
           |     |-- qextserialport\
           |     |
 * Create a config.pri file, and put into qextserialport's directory.
           |-- yourpath\
           |     |-- qextserialport\
           |     |     |-- config.pri
           
   * Contents of config_example.pri
  
           # uncomment the following line if you want to use qesp as library
           # QEXTSERIALPORT_LIBRARY = yes
           # uncomment the following line too if you want to use it as static library
           # QEXTSERIALPORT_STATIC = yes
 * Goto qextserialport/buildlib, and run following command to generate library.
           qmake
           make (or nmake)
 * Add following line to your qmake project file. Enjoy it!
           include(pathToQextserialport/src/qextserialport.pri)
== How to use (3) ==
Someone complains that, I want to used !QextSerialPort as a shared libaray, but
I don't want to add the {{{include(***.pri)}}} to my project file. Otherwise,
all the source files of !QextSerialPort will be shown in Qt Creator, which is
very annoying.
Ok, let's go!
 * Download the source code, and put it in any location you like.
 * Goto qextserialport/buildlib, and run following command to generate library. (Yes, config.pri is not needed.)
          qmake
          make (or nmake)
 * Add following lines to your .pro file. And you need to specify the path to the lib and headers. Then Enjoy it!
          # Specify lib and headers path if they are not in standard locations.
          # Otherwise, your can ignore this.
          unix{
             QEXTSERIALPORT_LIBDIR = #path_to_qextserialport_lib
             QEXTSERIALPORT_INCDIR = #path_to_qextserialport_headers
          }else{
             QEXTSERIALPORT_LIBDIR = #path_to_qextserialport_lib
             QEXTSERIALPORT_INCDIR = #path_to_qextserialport_headers
          }
          SAVE_TEMPLATE = $$TEMPLATE
          TEMPLATE = fakelib
          QEXTSERIALPORT_LIBNAME = $$qtLibraryTarget(qextserialport-1.2)
          TEMPLATE = $$SAVE_TEMPLATE
          INCLUDEPATH += $$QEXTSERIALPORT_INCDIR
          LIBS += -L$$QEXTSERIALPORT_LIBDIR -l$$QEXTSERIALPORT_LIBNAME
          DEFINES += QEXTSERIALPORT_USING_SHARED
          unix:QMAKE_RPATHDIR += $$QEXTSERIALPORT_LIBDIR
 * Oh, this file looks a bit complicated, as we need cross-platform. If you don't care cross-platform. It will be very simple :-) , for example
      
          INCLUDEPATH += /home/xxxx/download/qextserialport/src
          LIBS += /home/xxxx/download/qextserialport/lib/libqextsrialport-1.2.so
          DEFINES += QEXTSERIALPORT_USING_SHARED
 * Note:
  * If you do not want to add such lines to each of your projects. This is another solution too.
  * Create a new file called *extserialport.prf* , then add above lines to this new file.
  * Put this .prf file to one of feature paths, such as
          
          $QTDIR\mkspecs\features\
          
  * Add the following line to your .pro file. Enjoy it!
          CONFIG += extserialport
== Build (optional) ==
 * Run qmake from the toplevel directory.(If your has create a config.pri file properly, this will generate the library, and then all examples will use the library. Otherwise, qextserialport will be directly compiled into the examples)
           qmake (or qmake -r)
           make (or nmake)
 * Run qdoc3 from the doc directory.
           qdoc3 qextserialport.qdocconf
