1. TFU> SHOW TERMINAL TXB0: /FALLBACK/FULL

   TFF status for physical terminal _TXB0:

    Active tables:
      ASCII           (FALLBACK)
      LATIN_1         (compose sequence validation)

    Autocompose-keys (Parenthesized values are character's decimal value):
      None

    Settable flags:
      Nosuspend, Noaccept_8bit, Soft_compose, Signal, NoGR_terminal
    Internal state flags:
      None

    Rom(s) that will trigger TFF I/O conversion:
      ASCII
    Escape sequence parsing states:
      Input_state: Off (0), Output_state: Off (0)
      Terminal graphic registers for the next character (setup = VT00):
         G0 = ASCII,   G1 = ASCII
      Output mapping:
        GL = G0 (maps 7-bit; 8th bit is truncated)
    Output formatter expansion:
      Received:  4579  Transmitted: 4579 Expansion rate: +0.0%
