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. ----- Version 2.4d10 6/10/92 ----- 1. Replaced "Sys Req" with "Enter" in the "Function Keys" menu and in the "Double Click..." settings. "Enter" is useful as a double-click function when using menus in CMS, SAS, and other programs. 2. Fixed a bug in which appears to result from MacTCP changing the current heap zone. 3. Changed the code which handles selector pen fields to set the MDT bit when a field starting with blank or null is selected. ----- Version 2.4d11 6/11/92 ----- 1. Replace "Insert Char" with "Cursor Select" (which allows keyboard simulation of a selector light pen) in the "Function Keys" menu and the mouse double-click dialog. ----- Version 2.4d12 10/14/92 ----- 1. Fixed a bug which caused menu key equivalents to be ignored in some cases. 2. Corrected alignment problems with "print screen" output. Text will now properly line up in columns. However, it was necessary to map the reverse, underline, and frame display attributes to underlining when printing. Also, underlining will extend somewhat past the end of the underlined field, with the error being greater the longer the field is. This is an inherent problem in how printing currently works, and cannot be fixed by changes to tn3270. 3. Changed the maximum line width for WMAC printing from 132 to 256. 4. Fixed a bug which prevented saved row and column numbers in the new settings file format from being allowed to exceed 127. 5. Changed the icon for tn3270's settings files. Previous versions were using the icon which is intended for a tn3270 preferences file, which will be used by a future version. ---- Version 2.4a3 02/26/93 ----- 1. A new Open Connection dialog in the File menu replaces the previous Open Connection and Configure Connection menu items. The dialog has been redesigned to allow sessions and their settings to be managed more easily, and includes the ability to open a new session using settings from an active session. Numerous other small changes have been made in order to improve the management of settings. 2. tn3270 now supports a "tn3270 preferences" file for saving a set of default settings. The file is written when the new Save Defaults item in the File menu is selected. When tn3270 is launched, if the file "tn3270 preferences" exists in System Folder, or Preferences folder for System 7, the settings it contains will become the tn3270 defaults. 3. The ability to create "standalone" sessions has been added. These are sessions which have no host connection, but otherwise behave normally with respect to 3270 keyboard functions, Edit menu functions, and other features in tn3270. They are useful as scratchpads, similarly to how the clipboard can be used. To create a standalone session, select the "standalone" connection type using the "Special" icon in the Open Connection dialog. 4. tn3270 will respond to the required Apple Events under System 7. The most useful of these is the Open Document event, which can be used to create a new session using a settings file. 5. The library keyboard mapping has been changed to use the option key instead of the command key in order to generate many of the special library characters. Also, references to "ALA" in tn3270 have been changed to "library". 6. Numerous changes have been made in an ongoing effort to make tn3270 conform more closely to Apple's current human interface guidelines. 7. The debugging code in tn3270 has been changed to communicate with a separate debugger, instead of using a RAM disk. The debugger is still being developer. However, a preliminary version is available by contacting the author. ---- Version 2.4a4 04/28/93 ----- 1. Fixed a bug which caused items in the Network menu to be enabled incorrectly. Certain items apply only to TCP/IP connections, and were also being enabled for standalone connections. 2. Fixed a bug with cursor positioning: if the mouse was at the extreme left of the window, a click would move the cursor to the rightmost position. 3. Made several updates to the KeyMap program: a. Changed some dialogs to follow Macintosh user interface guidelines better. Also, a "watch" cursor will appear while a new definition file is being processed. b. "Display Keystroke Information" has been added to the "File" menu. This new function allows determination of the ASCII and raw key codes for keys by pressing them while the function is enabled. c. Greatly speeded up the processing of files by adding I/O buffering. d. Added a test to check if a mapping definition omits EBCDIC mappings for the ASCII codes between X'20' and X'7E'. A warning is issued listing those codes not mapped. This test is necessary because "Paste" will ignore any ASCII codes for which the current keyboard mapping does not define an EBCDIC equivalent. e. Added support for a new statement, "defchar name = value". This statement defines a new character named "name", which causes "value" to be sent as its EBCDIC value to the host. For example, the sequence of statements: defchar bullet = af bullet = '*' would case hex AF to be sent to the host when a key which generates the ASCII code for "*" is pressed. f. The "About" box was updated to show how much storage is available. 4. Added a new "no-op" function for key mappings. This function allows mapping a give key combination explicitly to be ignored. It is useful for solving some special key mappings problems, such as causing a key on the keypad to be ignored, while still providing an ASCII to EBCDIC mapping for the ASCII code the key generates. (The ASCII mapping may be needed for "Paste", as described in 3d above.) 5. Changed the "Paste" code to work correctly with mappings defined by "defchar". 6. Changed color table handling to restore the default color table after the last session is closed. Color table handling has also been improved to work better when only 16 colors are available. 7. RMAC and WMAC file transfers may now be initiated while tn3270 is in the background. If a standard file dialog must be presented, tn3270 will use the Notification Manager to inform the user that the transfer cannot proceed until tn3270 is in the foreground. 8. If tn3270 is launched with a preferences file instead of a settings file, it will not open a connection or present the Open Connection dialog. Instead, the settings in the preferences file will override any preferences file found in the System Folder. 9. Changed the keyboard mapping code to take into account differences in the ASCII codes for certain "Option" key combinations between System 7 and earlier versions of the system software. When older versions of system software are in use, tn3270 translates the ASCII codes to the System 7 values before performing key mappings. As a result, keyboard mapping defintions should always use the System 7 ASCII codes. 10. Changed the printing code to explicitly check if the current printer has changed while tn3270 has been active. This update should eliminate problems related to selecting a new printer while running tn3270. 11. The "Extended Features" dialog in the "Open Connection" dialog now includes a setting for "Pretend to support programmed symbols."
