Problems on QT SerialPort
-
Dear all
I am trying to communicate to a RS232 device. I used the example code 'simple terminal', everything works fine, I can send and receive messages. But, when I tried my code, it`s not working when I try to send messages. The receive part is working (because I trig the deceive with terminal first, and the deceive replies continually.)
I did it like this:
QByteArray msg = "COM,1";
serial->write(msg );But, nothing happens at all, I`m not sure is the deceive receive the message or not, and also, how to send <CR> at the end of the message?
Thanks in advance!

Hi and welcome to devnet,
Without any code, it's pretty much Crystal Ball debugging. However the first thing that jumps to mind is a misconfigured port. Also did you check that you can open it successfully ?
