   4:  * C:Itoh Prowriter (dot matrix) 10 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, EscN sets 10-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, EscN, 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.
