Looking for some good old DEC Ultrix and VAX VMS references gives some hints
for this legacy character set used in the default standard VT1xx to VT3xx
terminal emulations (note that now, most terminal emulators prefer to use
ISO-8859-1 by default, instead of DEC-MCS, sometimes available only as an
option):
- ISO 8859-1 National Character Set FAQ
http://www.ciesin.ee/OTHER/NCS-FAQ
(many other sources found in Google for the same FAQ)
- Message Exchange for VMS 5.5+ Release Notes
http://www.tmk.com/ftp/ftp-madgoat-com/mx/mx052/mx052.release_notes
Note also that the glibc NLS support (gconv) tables include a good table to
support DEC-MCS...
See also RFC1340 "Assigned Numbers" by J.Reynolds & J.Postel (published july
1992) page 80 of 139 (was STANDARD, obsoletes RFC1060, obsoleted by RFC1700;
now HISTORIC): it is listed with reference:
[170,KSX2]: Simonsen, K., "Character Mnemonics & Character Sets",
RFC 1345, Rationel Almen Planlaegning, June 1992.
Now looking in RFC 1345, I see this text:
&charset DEC-MCS
&rem VAX/VMS User's Manual, Order Number: AI-Y517A-TE, April 1986.
&alias dec

This seems authoritative, but the mnemonics used in that RFC aren't clear...
Well, that RFC 1345 was (and still is) INFORMATIVE...
