tc(1)                                                       tc(1)



     NAME
          tc - interpret troff output for use  at  a  vintage  display
          device

     SYNOPSIS
          tc [-t] [-o list] [-a n] [-e] [file] ...

     DESCRIPTION
          tc interprets its input (standard input default) as output
          from troff(1).  The standard output of tc is intended for a
          TEKTRONIX 4015 (a 4014 terminal with ASCII and APL character
          sets).  The various typeface sizes are mapped into the
          4014's four sizes; the entire troff character set is drawn
          with the 4014's character generator, by using overstruck
          combinations where necessary, producing an altogether
          displeasing effect.

          Typical usage is

             troff troff-options file | tc

          At the end of each page, tc waits for a newline (empty line)
          from the keyboard before continuing to the next page.  In
          this wait state, the following commands are recognized.

          !cmd   Send cmd to the shell.

          e      Invert the state of the screen erase.

          n      Print page n (previously printed).

          -n     Skip backward n pages.

          olist  Set -o list to list.

          p      Print current page again.

          an     Set the aspect ratio to n.

          ?      Print list of available options.

          The flag options are

          -t       Do not wait between pages (for directing output
                   into a file).

          -o list  Print only the pages enumerated in list.  The list
                   consists of pages and page ranges (for example,
                   5-17) separated by commas.  The range n- goes from
                   n to the end; the range -n goes from the beginning
                   to and including page n.

          -a n     Set the aspect ratio to n; default is 1.5.

     BUGS
          Font distinctions are lost.

          tc needs a -w flag option to wait for input to arrive.
