Thank you for downloading NCSAÊTelnetÊ3.0, now renamed to MacTelnet (since the PC version has not been updated).  As of version 3.0, MacTelnet is no longer a product of NCSA.  Please direct all inquiries regarding new versions of this product to me, Kevin Grant (kmg@mac.com).

IMPORTANT

MacTelnet is not finished software, and should only be used for trial purposes.  This is a ÒbetaÓ.  It is not optimized, and could cause your computer to crash due to an unexpected error.  It may or may not be compatible with prior releases.  The risk of using MacTelnet at this stage is 100% yours.

If you require a telnet application for regular use, you should not necessarily use MacTelnet (yet), for all of the reasons above.  Please download the previous Òfinal qualityÓ release, NCSAÊTelnet 2.6, from http://www.mactelnet.com/.

System Requirements

You must have a PowerPC-based Macintosh to use MacTelnet.  This includes any Mac built in the last 5 or 6 years.  In addition, you must have Internet connectivity software and the proper equipment (such as a modem).

Pre-release versions of MacTelnet are expected to run on Macs with Mac OS 8.x, but have not been tested extensively on most OS versions because I lack a lot of test machines.  Please report any problems immediately.

Packing List

The MacTelnetÊFolder contains a number of files and folders, all of which are non-critical.  Most of them are described below.

The items include, among other things:

Installation

This release of MacTelnet is simpler to install than previous releases!  MacTelnet can be installed anywhere you like Ñ simply drag and drop its folder icon to the desired location.

Preferences Fixer

This release of MacTelnet comes with a preferences fixer that users upgrading from any 3.0 version between 3.0a1 and 3.0a18 MUST RUN in order to retain existing preferences from previous releases.  The preferences fixer is named ÒUpdate Older MacTelnet PrefsÓ.  If you do not run the fixer program first, and you have existing MacTelnet preferences in your Preferences folder, MacTelnet will fail to start up, citing problems in creating a preferences file.

Note: If the fixer does not work, or if you experience unexpected problems upgrading from a previous release of MacTelnet, you can simply delete any existing MacTelnet Preferences in your Preferences folder (in the System Folder) to get MacTelnet to run.

The Fixer performs the following changes, if necessary:

WhatÕs New

First of all, I would like to apologize for Classic users for waiting so long to make an update.  But, here it is!

This update folds in some capabilities you may have first seen if you downloaded the Mac OS X Previews of MacTelnet from MacTelnet.com.

Bug fixes:

Enhanced tools are available: The menu interface has been revised: Other changes:

Tuning MacTelnet For Optimal Performance

MacTelnet can render onscreen information with varying degrees of sophistication and speed, depending upon the available memory and graphics hardware.  This allows MacTelnet to implement dynamic resizing of windows with smooth, fluid motion, and rapidly change a series of graphics objects with no ÒflickeringÓ.  On computers with minimal resources for graphics or less memory, MacTelnet automatically scales back its graphics engine, and will finally resort to incremental graphics drawing if it cannot do anything better (however, this results in a flickering effect).  On computers with many resources and QuickTime installed, MacTelnet can render graphics very smoothly.

MacTelnet has a huge preferred memory size because operations such as dynamic window resizing work best when there is plenty of memory available.  Increasing memory is not required, however Ñ MacTelnet will operate safely even in low memory conditions, and within its minimum partition.

If your monitor is set to a depth of ÒthousandsÓ or ÒmillionsÓ of colors, or if you have a very large monitor, you will definitely benefit by increasing MacTelnetÕs memory partition.  An increase of 1000ÊK or more is highly recommended to improve graphics performance in MacTelnet.  On the other hand, if you donÕt use the DynamicÊWindowÊResizing preference and have a small monitor, you shouldnÕt need to change MacTelnetÕs memory partition (and you may wish to reduce it to the minimum size).

For More Information

As always, MacTelnetÊHelp contains a wealth of information.  If youÕre lost, or you want more detail on a topic than is provided by MacTelnet itself, be sure to open MacTelnetÊHelp.  You can use any web browser to view MacTelnetÊHelp, or you can use the HelpÊViewer application that comes with MacÊOSÊ8.6 and beyond.  If you have installed MacTelnetÊHelp properly, you will be able to access it directly from the Help menu in MacTelnet (and you will be able to find context-sensitive help by clicking on question-mark (?) buttons in MacTelnet dialog boxes).  Or, view it online at http://www.mactelnet.com/.

The Open-Source Project

Did you know that MacTelnet is Òopen sourceÓ and Òfree softwareÓ (under the industryÕs most popular licenses from TheÊGNUÊProject at http://www.gnu.org/)?  Did you know that even companies can freely use MacTelnetÕs application-independent runtime library code?  Are you interested in contributing?  For details, visit MacTelnetÕs project web site at http://www.mactelnet.com/.
