Video selection is based upon an initialization routine that scans the keyboard and serial line to determine which video mode to use. If a character comes first over the serial line, then serial I/O will be used. If a key is detected on a port 7 keyboard (Elf II) then 1861 mode is used, If a key is detected on port 5 (Super Elf) then the 6847 video mode is used.
