Unable to open the port on MAC

[SteMMo33]

Describe the bug
I'm not able to open the serial port on MAC 12.7.4 and Qt.

From my code I get all the serial ports recalling the function QSerialPortInfo::availablePorts()
This call returns always couples of ports: example:

">> 'cu.Bluetooth-Incoming-Port' - loc: '/dev/cu.Bluetooth-Incoming-Port' - desc: ''"
">> 'tty.Bluetooth-Incoming-Port' - loc: '/dev/tty.Bluetooth-Incoming-Port' - desc: ''"
">> 'cu.usbmodem00000000001A1' - loc: '/dev/cu.usbmodem00000000001A1' - desc: 'VIOS118 ComPort'"
">> 'tty.usbmodem00000000001A1' - loc: '/dev/tty.usbmodem00000000001A1' - desc: 'VIOS118 ComPort'"

If I open a port I always have an error, regardless the selected port:

TerminalProt] Open '/dev/cu.usbmodem00000000001A1'
open port error: Unable to open : No such file or directory
[TerminalProt] Open ret: 0

[TerminalProt] Open '/dev/tty.usbmodem00000000001A1'
open port error: Unable to open : No such file or directory
TerminalProt] Open ret: 0

The code is very simply:

               std::cout << "[TerminalProt] Open '" << serial_port_parameters.PortName << "'" << std::endl;

		if (_serialPort.isOpen())
			_serialPort.close();
                _serialPort.setPortName(serial_port_parameters.PortName.c_str());
		bool ret = _serialPort.open();
		std::cout << "[TerminalProt] Open ret: " << ret << std::endl;

Please, any idea?
Thanks!

Could you test the example CommQT( or CommNoGui) of CSerialPort v4.3.1 ?
The example project at CSerialPort/examples/CommQT.
CommNoGui is console(no gui) example, and default output more debug info.

Hello, sorry for my delay.
This is the results of my tests.

-- Windows --
Everything is running ok.

-- MAC --
I need to apply a conditioned code:

#ifdef WIN32
		ui->cmbSeriali->addItem(Port.portName() + " - " + Port.description(), Port.portName());
#elif defined __APPLE__
		ui->cmbSeriali->addItem(Port.portName() + " - " + Port.description(), Port.systemLocation());
#endif

cause MAC uses systemLocation as 'device' name.
This is some of my debug info:

Effectively I absolutely need a 'non standard' baud rate (1177): but under Windows I don't have this problem, is it a MAC problem??

Thanks

[itas109]

non standard baud rate only support windows and linux now.
I need some time to support it on macos.

[SteMMo33]

ok itas109,
thanks.

Anyway, I'm using the package by vcpkg and right now there the version is one step behind.
(I don't know the dynamics for the deploy on vcpkg ...)
Thanks!

[itas109]

Mac OS X Tiger(10.4.11) support non-standard baud rate.

You could try the master code.

vcpkg get github master

vcpkg install cserialport --head

[SteMMo33]

stefano@MacMiniNewdep vcpkg % vcpkg install cserialport --head

The following packages are already installed:
    cserialport:x64-osx@4.3.0#1

but it is not aligned with the version on GitHub (4.3.1)

[itas109]

try remove fisrt, then install --head

vcpkg remove cserialport
vcpkg install cserialport --head

[SteMMo33]

Here I'm under Windows but again the installed version is 4.3.0#1
