What about the <enter> key ?

Maybe you need to pass options about the serial terminal features. The 
GRUB documentation mentions a --dumb option for non-VT100 compatible 
terminals, but it is not clear which command it applies to.

gfxterm is only valid as terminal_output, so you may need to split in two:

GRUB_TERMINAL_INPUT="console serial"
GRUB_TERMINAL_OUTPUT="console gfxterm serial"
