The EFI subsystems needs to know the size of the terminal. If the environment variable

stdout = serial,vidconsole

this size cannot be read from the video console. So the EFI subsystem sends escape sequences to read the size. With this patch we get support for the following escape sequences:

ESC "7" Save cursor position ESC "8" Restore cursor position
