HI Denis,

Thanks for the reply.

Even if I don't use "waitForReadyRead" but polling "bytesAvailable" instead,  the later always returns 0 although there is data received and I can use other terminal software to display it too.
Best regards,

I found a strange issue, when I read from serial, first I will call "waitForReadyRead", it returns with true in specified time, however, when I call "read" function thereafter, I can't read even a byte. the hardware works fine since I checked it by logic analyzer.

env: win7 64, qt 5.1 mingw version
