I have an application that I originally wrote with Qt 5.2 and have recently upgraded to Qt 5.10. I have a requirement to host in RHEL 7.3 and that system is using 5.10. That said my app works fine communicating with the serial device (GPS Receiver) when compiled using 5.2 but with 5.10 the writes are not being received. I am getting this same behavior in both Windows 10 and RHEL. Under Windows, using a Serial Port Sniffer (HDDsoftware), the output messages are being sent but not accepted/processed by the receiver. I have no visibility into the receiver. I am receiving input data without issue. I cannot find any version history for QSerialPort that might lead to a solution. Any suggestions would be appreciated. Thank you.
