Qt serialport does not work with RS422 but seems to work seamlessly with RS232

I am developing an GUI application in Qt to communicate to a device through RS422. All other connection application ( e.g., TeraTerm, Putty and hyper term ) seem to work with RS422 connection but not my Qt GUI communicating over serial port using 'QtSerialPort/QSerialPort' API. But this was resolved when we connected a RS422-RS232 converter and made a RS232 communication. Any idea why this might be happening?
It's a different protocol and Qt documentation only talks about RS232. So I think RS422 has been intentionally left out. Maybe it was due to lack of manpower or lack of interest - that I don't know.
Any idea why this might be happening?
What does not work? Please be more informative.
