function keys for emacs on a Linux VM

I have been using emacs for many years, and I have several common commands mapped to the function keys (at the top of the keyboard) for convenience. I am now trying to use emacs on a Red Hat 8 Linux virtual machine (VMware) under Windows. I am finding that I have to press the fn key (at the bottom of the keyboard) before I can use the function keys, which I never had to do before. This is a huge annoyance for me. Is there a way to make the function keys active without having to first hit the fn key? Thanks.
