[SOLVED] QSerialPort: CTS/RTS pinout checking

  • Hey,
    I'm pretty new to the Qt Framework and as far as working at the GUI everything works fine for now.
    I want to send a signal (only the RTS/CTS-part) via QSerialPort through my COM1. On the other side is a bridged (Pin 7 and 8, the two for RTS and CTS) serial port.
    Normally if I send a message that would be the first step, wouldn't it?
    It's only a studying case, but I don't know really where to start. It should be signal out and signal in or am I wrong?


  • To be more precise, I'm working on a 64bit windows7 system.
    The simple idea of this whole thing is that I try to check if the RTS gets somewhere and want to get the CTS-signal instead without building a new device with implemented logic
