+.SH NAME
+ascii \- ASCII character set encoded in octal, decimal,
+and hexadecimal
+.SH DESCRIPTION
+ASCII is the American Standard Code for Information Interchange.
+It is a 7-bit code.
+Many 8-bit codes (e.g., ISO/IEC\~8859-1) contain ASCII as their lower half.
+The international counterpart of ASCII is known as ISO/IEC\~646-IRV.
+.P
+The following table contains the 128 ASCII characters.

+.SH NOTES
+.SS History
+/etc/ascii (VII) appears in the UNIX Programmer's Manual.
+.P
+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.
+.P
+Uppercase and lowercase characters differ by just one bit and the
+ASCII character 2 differs from the double quote by just one bit, too.
+That made it much easier to encode characters mechanically or with a
+non-microcontroller-based electronic keyboard and that pairing was found
+on old teletypes.
+.P
+The ASCII standard was published by the United States of America
+Standards Institute (USASI) in 1968.
+.\"
+.\" ASA was the American Standards Association and X3 was an ASA sectional
+.\" committee on computers and data processing. Its name changed to
+.\" American National Standards Committee X3 (ANSC-X3) and now it is known
+.\" as Accredited Standards Committee X3 (ASC X3). It is accredited by ANSI
+.\" and administered by ITI. The subcommittee X3.2 worked on coded
+.\" character sets; the task group working on ASCII appears to have been
+.\" designated X3.2.4. In 1966, ASA became the United States of America
+.\" Standards Institute (USASI) and published ASCII in 1968. It became the
+.\" American National Standards Institute (ANSI) in 1969 and is the
+.\" U.S. member body of ISO; private and nonprofit.
