New Features in tcl3270 3.3
tcl3270 3.3 is the current development line for tcl3270.
Changes in tcl3270 3.3.6, 23. June 2007
- Bug Fixes:
- The code now builds with ICU 3.6.
- Removed the -mono option and mono resource.
- New Features:
- Added proxy support via the -proxy option or the proxy
resource.
- Modified Blank Fill mode to treat trailing underscore
chararacters ('_') like blanks when checking for input
overflow.
Changes in x3270 3.3.5, 1. February 2007
- Bug Fixes:
- Fixed a scripting hang when the host disconnects during
Wait(output)).
- Fixed a problem where unlockDelay could result in the
keyboard never unlocking, if the host unlocked the keyboard
often enough.
- Added a workaround for very old snprintf()
implementations.
- Fixed a problem with the Wait action in the expect glue.
(Thanks to Jason Howk for the fix.)
- Fixed a problem with CR/LF translation on ASCII file transfers.
- New Features:
Changes in tcl3270 3.3.4, 10. April 2005
- Bug Fixes:
- The code once again builds on Cygwin and other systems not supporting
IPv6.
- Removed unintended blank-line suppression from the output of
PrintText html string.
- Restored the automatic keyboard unlock delay when processing a
macro or string. This allows macros and strings with embedded AID
sequences to work with hosts that unlock the keyboard before they
finish processing a command. Scripts are presumed to be able to
figure out when the host is finished, or can set the unlockDelay
resource to true get the delay all the time.
- Fixed an apparent hang (actually just extreme slowness) when the
host sends a message larger than 4 Kbytes on an SSL tunnel.
- Removed spurious 'Wait timed out' errors in the Wait
action.
- New Features:
- Added a newer, more flexible version of Don Russell's RPQNAMES
support.
- Added support for IPv6.
Changes in tcl3270 3.3.3, 31. December 2004
- Bug Fixes:
- Fixed the Transfer() action, which didn't work at all.
- Fixed the default primary/alternate screen size (it was alternate,
it's supposed to be primary).
- Fixed the output of NVT-mode ANSI line-drawing characters in the
Ascii() scripting action.
These were formerly all output as blanks; now they are output in
the same was as x3270 3.2.
- Fixed make depend.
- Fixed x3270_glue.expect, which got confused when there was
a whitespace-delimited double-quote in the emulator output.
- Fixed a scripting hang when an UNBIND command arrived while an AID
was pending.
- Fixed a problem with the incomplete processing of a NULLing Program
Tab order, which could leave formatting artifacts on the screen.
- Removed <subchar1> clauses in two of the .ucm files
that prevents later versions of ICU's makeconv from accepting
them, and removed DOS carriage-return characters from the CP837
.ucm file.
- Corrected some DFT-mode file upload problems: corrected the data
length, and corrected an empty-buffer problem when the file size was
an even multiple of the buffer size.
- Corrected a DBCS conversion problem with ICU 3.0.
- Added variable buffer-size support to DFT file transfers.
- Fixed a buffer overflow problem in the ReadBuffer action.
- Fixed garbage characters generated for APL data by the Ascii
and ReadBuffer actions.
- Allow 0 timeouts in Wait actions.
New Features:
- Added Don Russell's RPQNAMES support.
- Removed Minolta-copyrighted code, because of licensing problems.
- Added an aidWait toggle to allow AID actions (Clear,
Enter, PA and PF) to complete immediately without
waiting for the host to unlock the keyboard, and a Wait(Unlock)
action action to block a script until the keyboard is unlocked,
regardless of the state of the new toggle.
- Turned off the old scripting hack the delayed actually unlocking the
keyboard for 50ms after the host says we can unlock it. Added a
unlockDelay resource, which can be set to true to turn
it back on.
- Added a dftBufferSize resource to set the default DFT
buffer size.
- Added a Save Screen Text menu option to save the screen image
in a file, optionally in HTML.
- Added options to the PrintText action to save to a file, to save HTML,
and to return the text as script data.
Changes in tcl3270 3.3.2, 1. December 2003
- Bug Fixes:
- 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 tcl3270 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.
- Fixed idle commands. They were pretty much hopeless in 3.2.20.
- Fixed a Unicode conversion crash.
- 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.
- 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.
- New Features:
- Added a ReadBuffer() action to dump the entire contents of
the 3270 buffer, including field attributes and extended attributes.
- Added support for suppress resources for each menu item.
If set to True, that menu item will not appear.
- The TELNET START-TLS option is now supported.
- Four more Japanese host code pages have been added: 930, 939, 1390
and 1399. This uses new support for combined SBCS/DBCS code pages.
- 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:' prefix
on the hostname.
