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