Serial port print for html

Is this possible to print a dynamic html file through serial port printer line by line...?

Since a HTML file (and dynamic content generated by PHP etc) is text content, sure.

There's a new class in Qt5 that makes it fairly easy to deal with serial ports: "QtSerialPort":https://qt-project.org/doc/qt-5.1/qtserialport/qtserialport-index.html

That should get you going.

Im using Qt5.0, it does not have any class QtSerialPort. so im download source code from some other website and compile. it shows read and write function errors.. im follow instructions using this website(http://qt-project.org/wiki/QtSerialPort)..

Seems like you tried to run it? You should use QtSerialPort as a library.

If I recall correctly, after building it in Creator, go to the build directory in your terminal and type "make install"

i went to terminal window of specified build folder and i type make install or sudo make install, but shows make: nothing to be done for 'install', i also tried qmake... nothing happen, wats wrong with my code..!http://i41.tinypic.com/zmeb93.png(screenshot1)!

Well, perhaps it's already good to go.

Did you try using the library as described under "Usage" in the Wiki?
