ASCII 6/12 from NOS
===================

   This charset is available in `recode' under the name `CDC-NOS', with
`NOS' as an acceptable alias.

   This is one of the charsets in use on CDC Cyber NOS systems to
represent ASCII, sometimes named "NOS 6/12" code for coding ASCII.
This code is also known as "caret ASCII".  It is based on a six bits
character set in which small letters and control characters are coded
using a `^' escape and, sometimes, a `@' escape.

   The routines given here presume that the six bits code is already
expressed in ASCII by the communication channel, with embedded ASCII
`^' and `@' escapes.

   Here is a table showing which characters are being used to encode
each ASCII character.
