I could do that but device is far away from me so i cant test it. What you suggest me and do i need a 3rd party library or can i do that with qt tools ? I should to listen serial port when connected to pc with usb of pos device.
When i arrive that infos i will wrapped that values in database as synchronously. Just i don't know how the data will come. Maybe json or xml i need to go and test it. How i can sure ?
The first step would be to check the documentation of your device. They should provide you with that information.
And Qt has
to read/write to comports.
You can use this Demo to test the comm with the device if you get access to it.
