Grub over serial0

My console is of type Serial, which is great. But when I try to access the grub menu, it's just frozen, and I can't do anything else than booting the default.
Is it possible to select another Grub entry than the default when Display is set to Serial terminal 0 (serial0) ?

Thanks,
