I struggle communicating with a serial pressure sensor, so I'm seeking for help.
I've got documentation from the supplier explaining how to connect the sensor, and which command to send (I can share everything if needed).
When I send the command via RealTerm, the TXD indicator in the status panel quickly turns yellow and I have no answer from the device.
If everything was OK, it should turn green, right?
All other indicators are off.
Thanks a lot for you help guys.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Is it a USB device implemented by the manufacturer?
Some usb "serial" devices where the manufacturer "implemented" the usb serial (i.e just used some demo code from ST or something from stackoverflow that seemed to work most of the time), don't have correct driver implementations and don't work properly. (and this is why my product continues to use an FTDI chip despite the price)

I might also precise I set the HW flow control to none.

Does the port you are trying to use exist?
Is it showing up in device manager OK?
