  * @(no)
      EEPROM file io.
      no: 0~63 (when 1Mbit)
  * _
      Run the file '.' as FORTH or binary automatically.
  * ex.
      >cat . > uart
      >cat uart > .0
      >cat @0 > .1
      >cat .15 > @63
  + '_' will be ran by pushing the button at the system booting.
  + it will switchs mode console<->uart mutually when btn is pushed or ctrl+d is received.
     (can't use 'vi' in uart mode.)
 (echo)
 - A argument printer.
  * ex.
      >echo Hello World.
 (skl)
 - A keyboard layout setter. (us/jp)
  * ex.
      >skl jp
 (video)
 - A video mode setter. (0-8)
  * ex.
      >video 3
 (cat)
 - A input printer.
  * 'ESC'
      exit.
  * ex.
      >cat .
      >cat uart
      >cat -c 186 uart > .
 (ls)

  * ex.
      >vi .
      >vi @0
 (ts)
