How to reset broken stty after printed binary data?

I’m not sure if this is the right place to ask, but sometimes my terminal gets messed up inside gdb by e.g. printing binary data. If this happens in the shell, I can execute caommands like `$ stty sane` or `$ reset` (see https://www.commandlinefu.com/commands/view/32/salvage-a-borked-terminal for more info). I can't get these methods to work in gdb and I’m wondering if there is a way to salvage my session without exiting gdb. I’m running this on a clean Ubuntu 16.04 installation with gdb from the distro’s packages:

$ lsb_release -a
