O _ o DEL +.if t \{\ +.in +.ft P +\} +.fi +.SH NOTES +.SS History +/etc/ascii (VII) appears in the UNIX Programmer's Manual. +.PP +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. +.PP +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. +.PP +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. +.\" +.SH SEE ALSO +.BR charsets (7), +.BR iso_8859\-1 (7), +.BR iso_8859\-2 (7), +.BR iso_8859\-3 (7), +.BR iso_8859\-4 (7), +.BR iso_8859\-5 (7), +.BR iso_8859\-6 (7), +.BR iso_8859\-7 (7), +.BR iso_8859\-8 (7), +.BR iso_8859\-9 (7), +.BR iso_8859\-10 (7), +.BR iso_8859\-11 (7), +.BR iso_8859\-13 (7), +.BR iso_8859\-14 (7), +.BR iso_8859\-15 (7), +.BR iso_8859\-16 (7), +.BR utf\-8 (7) |
