      Hi,

      I have submitted a bug several day ago, but seems that others do not come with the similar problem.

      http://code.google.com/p/qextserialport/issues/detail?id=121

      So I do not how to do with this.

      However, I found a similar issue at stackoverflow which has been solved.

      http://stackoverflow.com/questions/9713656/qextserialport-drops-data-on-windows-what-can-i-do-about-it

      You can give a try to it.

          welcome to devnet

          There are at least two different Qt-based implementations available. There have been already a number of threads concerning the topic. One of the implementations or also both are mentioned in following threads with following tags:
          "QExtSerialPort":http://qt-project.org/search/tag/qextserialport
          "QSerialDevice":http://qt-project.org/search/tag/qserialdevice
          [edit]
          A good start might be "this overview":http://qt-project.org/forums/viewthread/16949

          Vote the answer(s) that helped you to solve your issue(s)

            for the information, I knowed about "QExtSerialPort", but the QSerialDevice can be the right for my project.

              bq. but the QSerialDevice can be the right for my project

              Instead of QSerialDevice - use "QtSerialPort":http://qt-project.org/wiki/QtSerialPort.
              QSerialDevice is no longer growing (develop is freezing). His code was used as the basis QtSerialPort. Now QtSerialPort is a child.

                Hi all,

                I have to work with serial port and need to to install it on my computer.
                What i have to do to install it?

                I download this:
                "qtplayground-qtserialport"

                from here:
                http://qt-project.org/wiki/QtSerialPort

                but I am a little confuse because the installing guide is for linux not for windows.
                How to install qt serial port on windows?

                Thanks!

                  What an embarrassment? Where does it say that only for Linux?

                  Read "it":http://qt-project.org/wiki/QtSerialPort#b55bbb687c599634cc785869b9167639 again

                      Hi everybody,

                      I createt tree windows with the QtDesigner and from windows one of them start the another windows,
                      from windows one I have connection to the another windows (include the header files), so I include the the header file from the windows one to the another windows to have connection from every window to the window one, but wenn I declare filetype from windows one I get the following error.
                      "Fehler:ISO C++ forbids declaration of 'Com_Net' with no type"

                      this is a C++ error, but I include the header files :-(((.

                      Wath cann I do to solve this problem.

                      Here is the header file from the another windows.

                      @#ifndef DICS_H
                      #define DICS_H

                      #include <QWidget>
                      #include <QSizePolicy>
                      #include <QMoveEvent>

                      #include "com_net.h" bq. here include the header files from the windows one
                      #include "ui_com_net.h"

                      namespace Ui {
                      class DICS;
                      }

                      class DICS : public QWidget
                      {
                      Q_OBJECT

                      public:
                      explicit DICS(QWidget *parent = 0);
                      ~DICS();

                      private slots:
                      void on_External_Button_clicked();
                      void on_Internal_Button_clicked();
                      void on_PABX_Button_clicked();
                      void on_PAS_Button_clicked();

                      private:
                      Ui::DICS *ui;
                      Com_Net *active_com_net; bq. and here is the pointer declaration from windows one.
                      virtual void moveEvent(QMoveEvent *event);
                      };

                      #endif // DICS_H@

                      Thanks very much, for the help.

                            Dear community,

                            I work with the "qextserialport-1.2beta2" and all work well, but I have one problem, I want to send in binary mode, ones I can set is "port->setTextModeEnabled(false);" but the serial port stil interpret the data "o" like a null terminator and so cut the string after the every "0".
                            my question is it possible to send by "qextserialport" binary mode, or I have to look for a another way.

                            thanks for the answer, :-))).
