10 Apr 95: Beta.14. Add full support for ISO 2022 character-set
switching for GL, GR: G0..G3, and for VT220 NRCs (National Replacement
Character Sets). Priorities adjusted and new command, SET PRIORITY, added
to allow user to modify. Full user control for TELNET binary mode:
SET TELNET BINARY-MODE { ACCEPTED, REFUSED, REQUESTED }
and of handling of carriage returns in both NVT and binary mode, to get
around inconsistent interpretations of binary mode (and NVT mode) by different
TELNET servers:
SET TELNET NEWLINE-MODE { NVT,BINARY-MODE } { ON,OFF,RAW }
