Describe the issue you encountered

I'm running an x86_64 program on my kali aarch64 vm using qemu-amd64 -g 1234. I have a working remote connection to the binary using gef-remote --qemu-user localhost 1234, I can set breakpoints and step through the binary. When I try breaking the program using Ctrl-C nothing happens except for the string ^C getting printed in the gdb console. I checked the remote interrupt-sequence and it's set to Ctrl-C.

Do you read the docs and look at previously closed issues/PRs for similar cases?
