NAME
       ascii - the ASCII character set encoded in octal, decimal, and hexadecimal

DESCRIPTION
       ASCII is the American Standard Code for Information Interchange.  It is a 7-bit code. Many
       8-bit codes (such as ISO 8859-1, the Linux default character set) contain ASCII	as  their
       lower half.  The international counterpart of ASCII is known as ISO 646.

       The following table contains the 128 ASCII characters.

       C program '\X' escapes are noted.

HISTORY
       An ascii manual page appeared in Version 7 AT&T UNIX.

       On  older  terminals,  the underscore code is displayed as a left arrow, called backarrow,
       the caret is displayed as an up-arrow and the vertical bar has a hole in the middle.

       Uppercase and lowercase characters differ by just one bit and the ASCII character  2  dif-
       fers from the double quote by just one bit, too.  That made it much easier to encode char-
       acters mechanically or with a non-microcontroller-based electronic keyboard and that pair-
       ing was found on old teletypes.

       The  ASCII  standard  was  published  by  the United States of America Standards Institute
       (USASI) in 1968.
