2/15/95 NCSA Telnet 2.6.1d7 for the Macintosh Release Notes
Brought to you by: Clint Popetz (cpopetz@ncsa.uiuc.edu)
Jim Browne (jbrowne@uiuc.edu) [departed 12/18/94]
These release notes contain the following information:
Ñ Changes since the last version
Ñ Telnet release schedule
Ñ Goals left for current release
Ñ Bug list
Ñ Future features list
Ñ Old changes list
Changes since 2.6.1d6
---------------------
Ñ Fixed Problem with backspace/delete in preferences->terminals dialog
Ñ Fixed crash on pre-sys7 machines due to 2.6.1d6 bug fix
Ñ Added Command-Clickable URL support
Ñ Added Internet-Config support
Ñ Added support for "rlogin://" GURL event.
Ñ Telnet no longer reports active connections dialog on quit when "windows
don't go away is on" and the only windows are dead
Ñ FTP server no longer shows invisible items
Ñ Fixed DragLib problem on pre-7.5 PPC machines
Ñ Fixed Meta-@ and Meta-^ for EMACS (There is a new Fixed Controls KCHR)
Ñ Fixed a resize problem created in d5
Ñ Added option in Terminals to remap the Numeric Keypad to its standard
(non-vt220) Mac behavior, ie the operators can be used and wont send PFs.
Notes on URL support:
---------------------
Helper Applications are only supported through Internet Config. Catch the wave.
Use Internet Config.
Command-Click in any part of a URL will select it and launch the helper, including
multiple line URLs. The following formats are supported:
scheme:
URL:scheme:
<scheme: >
<URL:scheme: >
"scheme: "
"URL: scheme: "
If you have spaces in your URL, surround it with <> and click in the first fragment
of it. Otherwise Telnet wont find it. However, if you select text manually, and
Command-Click within it, Telnet will try to use what you selected. (ie, it will
strip extra stuff, but won't go looking for a complete url) Basically, I mimic NW
in all this. (Including neat-o flashing on success)
Currently, only GURL aware helpers are supported. I didn't want to implement the
enormous headache of writing a prefs file for each non-GURL app, or put out a
new version each time someone new supports GURL, or add XXX's favorite ftp client
prefs format to telnet. So its GURL or nothing.
MUCH thanks to John Norstad's NW code to launch the most recent application of a
given sig; it now resides in Telnet.
Note on remap keypad option:
---------------------
Many people had complained that they never use the vt keys which look like operators
on the mac keypad. So, in Preferences->Sessions, you can override the VT definitions
so that the operators work.
Note on compiler compatability:
------------------------------------------
I have given up (for the time being) trying to make Telnet compile
under MPW and Think C. I am sticking with the most beautiful of environments,
Metrowerks CodeWarrior. If the day comes when all the bugs are fixed, I will try
to go back and make them compatible, but frankly, I would rather spend my time
fixing MY bugs and putting in new features than finding work-arounds for problems
in other development environments.
NCSA Telnet for the Macintosh release schedule:
-----------------------------------------------
Don't bet the farm on these dates. For entertainment purposes only.
2.7 Feb 1995 (very firm)
3.0 May, 1995 (somewhat firm)
This will probably be the last development version of 2.6.1. This means once
any new bugs fixed, expect 2.7 very soon.
Development of NCSA Telnet will continue through at least 3.0 and probably beyond.
Goals for 2.7:
----------------
Ñ Fix the VAX/VMS VT220 problems.
* Fix the NeXT interaction problems. (See below)
Ñ Clean up the segmentation a little bit more and do some memory cleanup.
In at least one NeXT running NeXTStep 3.2, the linemode implementation in telnet
works correctly. In others, it does not. If you are experiencing garbage characters
or immense lag, turn linemode off. This has also been verified to occur with linemode
implementations on Convex machines.
By 2.7, I am going to try to either fix the linemode problems or provide firm proof
that it is a problem on the other end.
If someone has a nice summary of the VAX/VMS vt220 problems, please mail it to
me, as the reports I have are sketchy and sometimes contradictory.
----
This is the list of all Telnet bugs known to NCSA, feel free to mail me if
you find others: (This is pretty much the same as last release)
Crashes:
Ñ Window positioning
Ñ Telnet doesn't constrain saved window positions to available desktop
Ñ When switching to 132 columns, window's right edge should stay on screen
Ñ Type during paste bug
Ñ Occasional problems getting the preferences to "stick"
Ñ Certain macro sequences are not sent correctly (?)
Ñ \r,\n, and \t cannot appear in a Macro sequence
Ñ Some interaction problems with NeXT systems (See above)
Ñ Capture text sometimes contains extra returns
Implementation:
Ñ Need to always set push flag when sending return
Ñ Reduce WDS sizes?
VT emulation:
Ñ VT220 insert mode problem
Ñ VT220 fn keys can still be sent while in vt100 mode
Ñ Problems w/VT emulation when connecting to certain VAX/VMS hosts
Ñ Screen trashing when forcesave is on
Ñ Bold font problems need to be solved
Ñ Tabs don't work completely
Ñ Clear whole text cell
FTP:
* FTP log not very useful for Macbinary transfers
* FTP server filename ISO tranlation not working?
Ñ FTP Server dropping characters in ASCII mode?
Ñ Need to add a provision for editing "anonymous"'s directory
Ñ Occasional MNetPush error when using FTP
Ñ FTP transfers occasionally creating zero size files
Ñ Multiple user/one password bug?
TEK:
Ñ Some TEK emulation bugs
For 3.0:
Ñ Modeless configuration interface
Ñ Modeless macro dialog box
Ñ Modeless Open Connection box (?)
Ñ Scriptable
Ñ Sessions can be configured to capture immediately from opening
Ñ Reverse DNS connecting FTP hosts
Ñ Better Key remapping features
Ñ ANSI color sequences
Ñ Save attributes in scrollback
Ñ Possible firewall support (See below)
Ñ Major internal re-working (See below)
Ñ Possible clean-up of TEK code (volunteers?)
Suggestions I don't think I will implement:
Ñ Different printer font than window font
I am interested in getting a consensus on what firewall methods are "standard."
With the use of Telnet as a helper app becoming more feasible with the support of
the GURL suite, and considering the need to move towards scriptability, an alternative
is needed to opening a connection to the firewall and then manually telnet-ing from
there. So, anyone interested in giving a firewall-idiot some pointers, feel free to
mail them to me (Clint). Please include "FIREWALL:" in the subject.
3.0 will be quite a major release, where I will continue the cleansing process that
Jim began. The memory management will be almost completely redone, and the scrollback
format will be reworked significantly. Now's the time for interested parties to
submit requests for things you're just dying to see in telnet. So, consider this the
official announcement of the "3.0 Telnet Wish List." Just mail to me (Clint) or to
mactelnet@ncsa.uiuc.edu, and please put "TELNET WISH: " in the subject.
The Documentation for 2.6 is FINALLY on line. It can be found at:

Old Changes
-----------
Changes since 2.6.1d5:
----------------------
Fixed bug that caused set files and macros not to load properly on startup
Fixed FTP server memory bug
Fixed FTP server 'put files that start with a period' bug (around since 2.6.1d1)
Added Send timeouts
Fixed bug that caused Telnet not to read old prefs files correctly
Fixed bug that caused setting of visibility of function key windows not to stick
The FTP server bug probably caused most of the crashes reported in d5, since the
server just had to be ON, not ACTIVE to cause problems.
Changes since 2.6.1d4
----------------------
Macros can be imported and exported to/from text files
User set-able Block Size
User set-able Send timeouts
User set-able font size (i.e. other than 9,12,etc.)
Fixed a PPC FTP server bug (existing since port to PPC)
Fixed (some) crashes under low memory resizing
Fixed a scrolling bug created in 2.6.1d4
Changes since 2.6.1d3:
----------------------
Drag and Drop support. Text can be dragged out of and into connection windows
Scrolling speed improvement. Scolling speed has been improved by about 5%
The FTP Client has been removed.
Telnet now uses less memory (changes to tek storage system)
Telnet now scans Extensions folder & the folder Telnet resides in for
Authentication/Encryption plugins
Fixed a corruption bug for files transferred in binary mode by the FTP server
Fixed a few TEK bugs
Added support for GetURL AppleEvent (only "telnet://" scheme supported)
Changes since 2.6.1d2:
Keypad and Function key menus added
Global pref added for Keypad and Function key menus
Toggle on VT type radio buttons in Terminal prefs fixed
Toggle on Paste and BS/Del buttons in Session prefs fixed
Changes since 2.6.1d1:
Authentication and Encryption now use plug in modules
Authentication and Encryption are available on the PPC
VT screen size display during window resize works on PowerPC version
Application is a fat binary
Changes since 2.6:
The port to PowerPC has almost been completed. Currently Authentication and
Encryption are not available while running on the PPC. 2.6.1d1PPC has been
quite stable for me. Please let me know if the PPC version shows any bugs
that aren't in the 68K version.
