Originally adapted to OS/2 by Chris Adie of Edinburgh University, Scotland
([email protected]), 1988, from the UNIX Kermit CONNECT module by Frank
da Cruz, Columbia University. VT102 terminal emulation originally by Chris
Adie, 1988 ("If the code looks a bit funny sometimes, it's because it was
machine translated to C.") (From what??)
Adapted to c-Kermit 5A by Kai Uwe Rommel ([email protected]),
1992-93 (present address: [email protected]).
Many changes by Frank da Cruz ([email protected]): numerous bug fixes (tabs,
cursor/attributes save/restore, scrolling, keypad modes, etc), new SET
TERMINAL commands, TCP/IP TELNET support, printer support, character-set
support, APC escape sequence handling, print/dump screen, complete rewrite
of character attribute handling & screen reversal and rollback, addition of
VT220 and ANSI emulations, keyboard verbs, Compose key, Hebrew features,
Cyrillic features, context-sensitive popup screens, cosmetic improvements,
commentary, etc: 1992-present. (Hopefully much of the funny-looking code
looks less funny now.)
Massive improvements by Jeffrey Altman <[email protected]>:
changes to keyboard handling, mouse support, ...: 1993 to present.
(191) new connect mode screen handling, scrollback, ...
(192) Win32 support, many new emulations, new keyboard scan codes, ... */
