portName incorrect in QExtPortInfo #184

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Which version of QextSerialPort are you using?

1.2

What steps will reproduce the problem?

  QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();

  foreach (QextPortInfo port, ports) {
    qDebug() << port.friendName << port.portName;
  }

What is the expected output? In my case:

  "MOXA USB Serial Port (COM2)" "COM2"

What do you see instead? In my case:

  "MOXA USB Serial Port (COM2)" "COM10"

What version of the product are you using? On what operating system?

  1.2, Windows 7 64-bit, Qt 4.8 MinGW

Please provide any additional information below.

  The port name is incorrect in the QextPortInfo structure. In my case, I have one device (a USB <-> serial adapter). It is on COM2. Device Manager reports name "MOXA USB Serial Port (COM2)". I can access it through QextSerialPort via the name "COM2". I can access it through other applications as "COM2". However, in the QextPortInfo, the port name is "COM10" (despite the name being correct). It is not "COM10" (nor is it "//./COM10")... it is "COM2".

  Consequently I cannot use any of the QextPortEnumerator features reliably, and cannot have my application provide a list of available ports to the user. The best I can do for now is assume the port number is in parentheses in the friendly name and parse it out.
