Hi
Very interesting project!
I've downloaded the QPort built it
and installed it under WindowsXP I've copied .dll and .a files to appropriate folders in my Qt 4.6.3 open source build
I have the widget in widgets list ( left panel in my QtDesigner)
I put it to my widget and only thing I see is text QPort and email adress
Please help me to use this
How can I use the widget?
What I can do with the widget?
Could you provide example of using it?
Sorry, i don't see your comment, if you wanna learn more about qport, you can visit my web page, www.sebest.com.ar, here you can find examples

If you need more help, post your question in forum (in english if you wanna).
Thank

This program locks up hard under OS X. I have modified it to use tty.KeySerial1 which is the Keyspan USB Serial converter device as follows:
comboBoxPortName->addItem("tty.KeySerial1", QVariant::fromValue(QString("/dev/tty.KeySerial1")));
comboBoxPortName->addItem("tty.USA19H3d1P1.1", QVariant::fromValue(QString("/dev/tty.USA19H3d1P1.1")));
The Keyspan devices works fine with ZTerm. The app hangs at the following line:
if (Posix_File->open(QIODevice::ReadWrite|QIODevice::Unbuffered))
In fact it hangs so bad that I can't even force-quit the app or kill the process. I have to reboot the machine.
Hello, I'm using the widget in ubuntu linux without problem, so use with a usb adapter with no problems. Particularly recommend that you put the name of the port from where QTDesigner says "Puerto" "/dev/ttyxxx". But since the code you can put qport->setPort("/dev/ttyxxx"). The error seems to not find the device.
Nope...still doesn't work. I checked the name of the device with qDebug right before it attempts to open:
from file "posix_qextserialport.cpp":
if (!isOpen()) {
/*open the port*/
qDebug() << port;
Posix_File->setFileName(port);
if (Posix_File->open(QIODevice::ReadWrite|QIODevice::Unbuffered)) {
/*set open mode*/
QIODevice::open(mode);
The app locks up so hard that I can't even force-quit it. I have to reboot the machine.
ok, tell which distribution you use, where can I download and I will try to see what the problem. I just tried it with ubuntu linux and I never had problems.
Ok, well, I hope that you can use without problems, just remember that it is a beta version, I have written a more stable function names in English and a small manual and a little more detailed.
In the coming days I will raise in qt-apps in my page. Any problems please consult.

I can compile, and use this widget in ubuntu linux.
But i have problem with windows. I cant compile, but doing any fix this is possible.
Im working in this fix and they be solve soom.
And, i don't know how to use dlls in windows for compile the example. Any people can help me?.

Sorry, you use mac os x, I never try this O.S.
Success, finally. Apparently Keyspan USB to Serial devices have both a tty. device and a cu. device. Changing it to cu. solved the problem.
