1. TFU> SET TERMINAL/FALLBACK=(ACCEPT, NOSIGNAL)

   The  command in this example enables fallback using system defaults,
   if  they are not already enabled. The option ACCEPT enables input of
   8-bit  characters;  NOSIGNAL  disables the terminal bell that sounds
   when invalid compose sequences are entered.

    2. TFU> SET TERMINAL/FALLBACK=(ACCEPT, TABLE:HANGUL_DS)

   The  command  in  this example  enables  fallback  for  the  current
   terminal, using the 16-bit character fallback table i.e.  HANGUL_DS,
   and input of 8-bit characters.

    3. TFU> SET TERMINAL TXB0: /FALLBACK=TABLE:NONE

   The  command  in  this  example disables fallback for terminal TXB0.
   This  is the same as SET TERMINAL/NOFALLBACK TXB0. Note that you can
   place qualifiers before or after the terminal-name parameter.
