Serial connection - Backspace not working

[archtur]

Steps to reproduce

1. Configure the serial port like in the pictures. Most relevant is IMHO the input mode Normal, because this is how I want to handle my shell that is on the connected device.

   • 

2. Write text

3. Press the backspace key.

The backspace key press does not delete the last written character, as expected.
I think backspace key (and possibly other relevant keys) are not send by tabby to the device. With other terminal emulators, this is working (e.g. teraterm). So the connected shell on the device can handle this.
