tn3270 updates since version 2.3d26:
----- Version 2.3d27 11/29/91 -----
1. Changed Erase EOF to work for unformatted screens instead of generating
an error.
----- Version 2.3d28 12/17/91 -----
1. Fixed a bug which caused the 3270 cursor to disappear in some cases when
graphics was being displayed. Now the cursor will always appear during
a graphics display, but may be an unusual color (even at times when the
cursor was a normal color before this change).
2. "Print Screen" now is available as a keyboard function in addition to
being in the "File" menu. The keyboard mappings supplied with tn3270
map "Print Screen" to shift-F13 (labelled "print screen") on the ADB
extended keyboard.
3. The "ala" keyboard mapping was renamed to "library", and the "ALA"
entries in the "National Language" menu were also renamed.
4. The "library" keyboard mapping was updated to allow entry of the single
and double dagger characters. There were also some other minor changes
to the keyboard mapping.
5. The names used to describe "library" characters in keyboard mappings
were changed to be clearer and more standard.
6. The ALA fonts were updated to display a double dagger for the X'1F'
code point.
----- Version 2.3d29 1/17/92 -----
1. Fixed a bug which caused tn3270 to crash when its window was dragged
so that none of the content part of the window was visible.
----- Version 2.4d0 1/04/92 -----
1. The tn3270 source code has been updated for MPW 3.2.
2. tn3270 is now linked with the BYU version of the NCSA TCP/IP code.
As a result, tn3270 includes additional bug fixes from BYU, and also
accepts additional keywords in config.tel added by BYU.
3. The code in tn3270 for the WMAC Print command now handles page range
selections more efficiently. Only the selected pages will be sent to the
print driver instead of all pages. However, all pages must still be
downloaded from the host.
----- Version 2.4d2 2/21/92 -----
1. Numerous, extensive changes were made in order to support multiple
sessions.
2. Paste will copy text from the clipboard to the screen at the current
cursor position. The text is treated as if it were entered from the
keyboard, with carriage returns being converted to 3270 newline
operations, and tabs converted to blanks.
----- Version 2.4d3 2/23/92 -----
1. Fixed a bug which caused a session to not be considered the "front"
session when the RMAC/WMAC status dialog was at the front.
2. Improved the performance of "Paste" and allowed it to work for more
than 2K of data.
----- Version 2.4d4 3/24/92 -----
1. Fixed a bug which caused tn3270 to crash when running on a Mac Plus
or other machines without Color Quickdraw.
----- Version 2.4d6 3/26/92 -----
1. Add support for tracing network write calls. The tracing is enabled
by using ResEdit to change the dashed line in the Network menu to
an enabled text item, such as "Show Write Info". Selecting the item
the first time will enable tracing. Subseuqent selections will show
saved information for several previous write calls.
----- Version 2.4d7 4/15/92 -----
1. For line mode connections, the Control and Escape keys will be
recognized on those keyboards which include them. The Command key
will generate control characters only on those keyboards without a
Control key.
2. Line mode keyboard handling has been made more efficient, so that
typed characters will no longer be lost.
3. tn3270 now uses a new, readable settings file format. Files in the new
format may be edited with word processing programs which have an "open
any file" option, or by temporarily changing the type of a file from
'GFTS' to 'TEXT'. Before returning to the Finder, tn3270 will ask if
you want to save settings read from an old format file in the new
format. All new settings file written by tn3270 will be in the new
format.
----- Version 2.4d8 4/21/92 -----
1. The keyboard mappings were changed so that the mapping for the "clear"
key does not also apply to the "esc" key. The "clear" key is now
mapped by key code instead of by ASCII code.
2. Changed the processing of the linefeed control character (in line mode)
to do a linefeed only, and not a carriage return as well.
----- Version 2.4d9 5/15/92 -----
1. tn3270 will no longer process host data continuously as long as any
is available. After 5 seconds it will return to the main event loop to
allow other processing to continue.
2. The code for tracing telnet option negotiation has been updated to
recognize the names of all currently-defined options.
3. The option negotiation code no longer recognizes the "TELOPT_3270"
option that had been added for test purposes.
4. The maximum number of session now defaults to 32, and is defined by
the MAXS resource number 128. The resource contains the maximum number
as a 16-bit integer. Any value between 1 and 512 is valid.
5. tn3270 now references its fonts by name instead of by number. Also, if
any of its fonts are present in the System file, those copies will be
used instead of the copies in tn3270. tn3270 will be able to use the
fonts in the System file even if installing them caused them to be
renumbered. As a result of these changes, storing copies of tn3270's
fonts in the System file will always be sufficient to ensure the fonts
are available for the Print Screen function.
6. Support for the graphics cursor and graphics input mode have been
added.
7. New key mappings have been added: Alt-Cursor default to Command-t,
and Graphics-Cursor defaults to Command-T. Alt-Cursor toggles the
text cursor between an underline and a block, and toggles the
graphics cursor between a cross and crosshairs. When the graphics
cursor is in use, Graphics-Cursor controls whether the cursor movement
keys are associated with the text cursor or the graphics cursor. When
the key are associated with the graphics cursor, "+Cr" appears in the
status line in the same position where the cursor position display
appears.
8. The graphics code has been improved, so that graphics will often
work well when no graphics bitmap has been allocated. However, the
bitmap is necessary for best performance, and is required in order
to save images in a PICT file.
9. tn3270 includes new icons which were contributed by Steve Klingsporn.
