       4:  * C:Itoh Prowriter (dot matrix) 12 pitch
       5:  * nroff driving table
       6:  * by G. Rochlin, 15feb83
       7:  * Because the c:itoh will backspace only in incremental mode,
       8:  * need to write a program to place commands Esc[ and Esc] around ^H.
       9:  * If you want true underline mode instead of _^Hx_^Hy, etc.,
      10:  * have the script first replace _^Hx with EscXxEscY, etc.
      11:  * Further refinements are possible to clean up files and
      12:  * minimize throughput (e.g., delete all EscYEscX pairs).
      13:  * In the terminal initialization (twinit) and exit (twrest)
      14:  * strings, EscE sets 12-pitch. Twrest clears by commanding
      15:  * Esc Y, Esc", and Esc$ to clear ul, bold, and "greek",
      16:  * Esc] to restore logic-seek print, Escf and EscT24 to restore
      17:  * forward linefeed at 6 lines/inch, Esc< for bidirectional
      18:  * print, EscE, and ^M (\015) to clear the print buffer.
      19:  * Since the itoh has no keyboard, you have to run it through
      20:  * a video terminal or micro printer port.
      21:  * The first twinit code (Esc`) and the last twrest code
      22:  * (Esca) set the (proper) "transparent" or "buffered" print
      23:  * mode for tvi950 and tvi925 and Freedom 100. This mode
      24:  * is necessary on intelligent terminals to keep all the Esc
      25:  * codes in the driver tables from scrambling the terminal's
      26:  * brains.  (If you have a dumb terminal, almost any print
      27:  * mode should be safe. Smart terminals without buffered print,
      28:  * such as the tvi920, present problems.)
      29:  * If you have a different terminal,
      30:  * the shell script should also replace these codes with those
      31:  * appropriate for your machine.  If you are using an sed
      32:  * stream for the script, make sure to use single quotes to
      33:  * isolate the ` from the shell.
