VT(1)                                                       VT(1)

          vt - emulate a VT-100 or VT-220 terminal

          vt [ -2abcrx ] [ -f font ] [ -l log ]

          Vt replaces a rio window with a fresh instance of the shell,
          rc(1), running within an emulation of a DEC VT-100 terminal.

          x  change vt to emulate a VT-220, ANSI, or XTerm terminal
          b  changes the color scheme to white text on a black back-
             ground, but potentially with colors from escape
          c  changes the color scheme to monochrome (no colors).
          f  sets the font.
          l  names a log file for the session.
          r  start in raw mode.

          The right button has a menu with the following entries to
          provide the sort of character processing expected by non-
          Plan 9 systems:

          24x80   Resize the vt window to hold 24 rows of 80 columns.
          crnl    Print a newline (linefeed) character after receiving
                  a carriage return from the host.
          cr      Do not print a newline after carriage return.
          nlcr    Print a carriage return after receiving a newline
                  from the host.
          nl      Do not print a carriage return after newline.
          raw     Enter raw (no echo, no interpretation) character
                  mode for input.
          cooked  Leave raw mode.
                  Toggle block selection for mode for rio snarf
          exit    Exit vt.

          The middle button has a menu with the following entries:

          backup     Move the display back one screenful.
          forward    Move the display forward one screenful.  (These
                     are a poor substitute for a scroll bar.)
          reset      Display the last screenful; the same as going
                     forward to the end.

     VT(1)                                                       VT(1)

          paste      Pastes the contents of the rio snarf buffer, just
                     as paste in the rio menu.
          snarf      Copy selection to the rio snarf buffer.
          plumb      Send selection to the plumber.
          scroll     Make new lines visible as they appear at the bot-
          page       When the page fills, pause and wait for a charac-
                     ter to be typed before proceeding.  The down
                     arrow key advances a page without sending the
                     character to the host.


          This program is used only for communicating with foreign
          systems, so it is not as rich an emulation as its equivalent
          in other environments.

          Use care in setting raw and newline modes when connecting to
          Unix systems via con(1). It may also be necessary to set the
          emulator into raw mode.
