I didn't think that'd work cuz I don't HAVE a menu, but it does!

After pressing 'c' while I'm in the "blank space", this is what I get in the 
Linux terminal

                          GNU GRUB  version 2.02~beta2

   Minimal BASH-like line editing is supported. For the first word, TAB   
   lists possible command completions. Anywhere else TAB lists possible   
   device or file completions. ESC at any time exits.                     

grub>  terminal_output
Active output terminals:
serial console 
Available output terminals:
serial_com0 vga_text spkmodem mda_text gfxterm cbmemc audio 
grub>  terminfo
Current terminfo types:
serial: vt100   ASCII   0x15
serial_com0: vt100      ASCII   0x0
