        !             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.
