Serial port number in windows

You can do with QextSerialPort. Example code:

@QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();
qDebug() << "SerialSettings::LoadPorts(): List of ports availables:\n";
for (int i = 0; i < ports.size(); i++) {
qDebug() << "port name: " << ports.at(i).portName;
qDebug() << "friendly name: " << ports.at(i).friendName;
qDebug() << "physical name: " << ports.at(i).physName;
qDebug() << "enumerator name: " << ports.at(i).enumName;
qDebug() << "===================================";
}

What is it?!?
When this function was added to the project?!?
QextSerialEnumerator?!? QextPortInfo?!?

It might just be me, but I don't see the classes mentioned in the code fragment in the documentation linked from the page you give. I am looking at http://qextserialport.sourceforge.net/qextserialport-1.1.x/

Is this new API? Newer than the latest API docs on the webpage?

stukdev · wrote on 27 Dec 2010, 11:57

This API is very strange!

Look this "http://code.google.com/p/qextserialport/source/browse/#hg/src":http://code.google.com/p/qextserialport/source/browse/#hg/src

The api version that i have downloaded is: qextserialport-1.2win-alpha (win version), you can download from here: http://sourceforge.net/projects/qextserialport/files/qextserialport alpha/

stukdev · wrote on 27 Dec 2010, 14:15

This is a new alpha API, that include enumerator :) Great news!

Yeap, hope that works for your app!

I trying this new api, but i don't understand why i have to make dll and not use the function in my application like the old version of api.

Well, i have worked with that api, using the dlls, do you mean that u need to link statically?

stukdev · wrote on 27 Dec 2010, 15:05

Yes, i use the old api in static mode, this api is writing for build shared library, look the macro
@

define QEXTSERIALPORT_EXPORT Q_DECL_EXPORT

@ in the code

Where is that definition?, i have never tried to link statically, but in the "qextserialport.pro" there is a line that says: #CONFIG += staticlib, have you tried to uncomment it?, and then compile it again( qmake, make)....

stukdev · wrote on 27 Dec 2010, 15:33

Yes, but many error give to me.
That line is in the class QextSerialEnumerator
@
class QEXTSERIALPORT_EXPORT QextSerialEnumerator : public QObject@

mmm Maybe i have a differente version, because the QextSerialEnumerator doenst inherit from QObject:

Version: qextserialport-1.2win-alpha, but i have downloaded many months ago (beggining of 2010).

stukdev · wrote on 27 Dec 2010, 16:18

The same of me, but you download it from sourceforge, me from googlecode.
Now i trying your lib, this not build a dll but the code you post don't display any port.
The same code work well in googlecode library with a dll.

I've used QSerialDevice to great success for other serial port tasks, it may be worth a look.

gronerth · wrote on 27 Dec 2010, 16:21

mmm from googlecode, thanks for the news...try to compile the example "enumerator" that it comes with the library...

stukdev · wrote on 27 Dec 2010, 16:23

Yes, i also use this library with success. But i think the 'enumeration' feature is in a very alpha state.
Only with a dll i can run correctly this feature.
