New Features in c3270 3.3
c3270 3.3 is the current development line for c3270.
It is functionally equivalent
to c3270 3.2.20, with the addition of SSL (Secure Sockets Layer) support and
DBCS (Double Byte Character Set) support for East Asian languages -- Chinese,
Japanese and Korean.
The DBCS work required a significant change in the internal workings of
c3270. For those familiar with the source code, the change was to store EBCDIC
codes internally, and to dispense with the confusing CG-code representation
of the 3270 display. This required changing all of the logic that manipulates
field attributes, as well as the logic that translates the host output, keyboard
input, and display output.
Changes in c3270 3.3.2, 1. December 2003
- Bug Fixes:
- Made configure more robust when it can't find one or the other
of libncurses or ncurses.h.
- Got automatic pr3287 start-up (-printlu) working again.
- Corrected a problem in x3270_glue.expect, which caused
Tcl syntax errors if a string began with a dash. Thanks to David
Taylor for the fix.
- New Features:
- Error messages are now written to the trace file.
- The response to the TELNET TIMING MARK option has been changed to
make it compatible with the majority of TELNET clients.
The response to DO TIMING MARK is now WONT TIMING MARK.
To restore the previous behavior (responding with WILL TIMING MARK,
originally derived from the BSD TELNET client), set the resource
x3270.bsdTm to true.
Changes in c3270 3.3.1alpha10, 7. September 2003
- Bug Fixes:
- Made nondisplay fields invisible to the Ascii() action.
- Corrected start-field values at the beginning of data stream traces
and in the 3270 Read Buffer response.
- Corrected a tight loop in the macro error cancellation logic.
- New Features:
- Added a ReadBuffer() action to dump the entire contents of
the 3270 buffer, including field attributes and extended attributes.
- Added a suppressActions resource, a list of the names of
actions to disable. This is primarily for controlled environments where
the user does not have access to the c3270 command line, but can
edit keymap definitions.
- Added a Setverbose function to x3270_glue.expect
to allow verbosity to be changed on the fly.

Changes in c3270 3.3.1alpha9, 25. July 2003
- Bug Fixes:
- Removed the concept of 'per-host' resources. Use profiles for
this.
- Fixed idle commands. They were pretty much hopeless in 3.3.1alpha8
and 3.2.20.
- Fixed a bug in processing the Modify Field order, which would cause
the character set attribute for the field to be accidentally reset to
the default.
- New Features:
- The TELNET START-TLS option is now supported.
Changes in c3270 3.3.1alpha8, 15. April 2003
- Bug Fixes:
- The EBCDIC notsign '¬' can now be entered with Ctrl-A,
^ (it formerly caused an error message).
- 3270-specific and NVT-mode-specific keymaps (e.g., keymap.base.3270)
are no longer ignored.
- When there is an ambiguous multi-character match in a keymap, the
correct matching keymap entry is now displayed in the keyboard event trace
file.
- Builds cleanly on Linux with -Wall -ansi -pedantic.
- Builds without OpenSSL libraries being present.
- Correctly records Field Attributes in the initial screen snapshot
in a Data Stream Trace file.
- Auto-Skip fields work properly.
- "Dead" positions in DBCS fields are handled correctly.
- Invalid host DBCS characters are handled better and are displayed
in the Data Stream Trace file.
- The Erase action now works properly with DBCS characters.
- The Visible Control Characters toggle now works properly.
- New Features:
- Ctrl-A, a is now mapped onto the Attn action in the
default 3270 keymap.
- Four more Japanese host code pages have been added: 930, 939, 1390
and 1399. This uses new support for combined SBCS/DBCS code pages.
Changes in c3270 3.3.1, 14. February 2003
- Bug Fixes:
- New Features:
- DBCS support for Simplfied Chinese and Japanese, including integration
with XIM.
- Tunneled SSL support added (entire Telnet session inside of an SSL
tunnel). Uses the OpenSSL library. Toggled with an 'l:' (ell) prefix
on the hostname.
