      NUL, AUX, CON, COM1-4, LPT1-3, and PRN
      are reserved words used for DOS Devices

      These are specified in IO.SYS and date back from the early MS Dos days. Here is a brief list:

      CLOCK$ - System clock
      CON - Console; combination of keyboard and screen to handle input and output
      AUX or COM1 - First serial communicationport
      COMn - Second, Third, ... communicationport
      LPT1 or PRN - First parallel port
      NUL - Dummy port, or the "null device" which we all know under Linux as /dev/null.
      CONFIG$ - Unknown

      So just like any programming language has reserved words, CON is reserved for a console device used by dos system.
      Hope this helps!
