 * shell to auto-set its DISPLAY.
 *
 * This particular sequence is even explicitly stated as obsolete since
 * about 1985, so only very old software is likely to be confused, a
 * confusion which can likely be remedied through termcap or TERM. Frankly,
 * I doubt anyone will even notice.  We provide a #ifdef just in case they
 * don't care about auto-display setting.  Just in case the ancient
 * software in question is broken enough to be case insensitive to the 'c'
 * character in the answerback string, we make the distinguishing
 * characteristic be capitalization of that character. The length of the
 * two strings should be the same so that identical read(2) calls may be
