Running Emacs without any display server

[Abhiseck Paira]

Hi,
I was trying to run Emacs without any display server (like Xorg or
wayland) (So I was running Emacs in a tty). Emacs started as expected
but the Alt (Meta) key wasn't working. So I couldn't do 'Alt-x' to do
'M-x' (so I had to do Esc-x instead). Similarly other key combinations
involving Alt key didn't work either (Alt-v, Alt-f etc). Does anyone
know why this is happeing or how to fix this?
