                      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.
