Popular Telnet App for System 9
One of the apps that I used to use a lot on my WallStreet PowerBook was BetterTelnet. This is an application that I used to connect into various networks for work and personal use.
With MacOS 10, you don't need BetterTelnet because you have the terminal to do any Telnet activities. Besides that, most sites now only have SSH enabled - secure telnet.
Official Product Description
BetterTelnet is a Telnet client for Mac OS prior to X (7/8/9), based upon the final release of the classic NCSA Telnet. The final BetterTelnet release is 2.0fc1. Jean-Pierre Stierlin maintained MacSSH for some time after BetterTelnet development ceased, and most users who happen to be stuck on a Mac OS 7/8/9 machine should probably look there instead. This page may eventually have some updates for MacSSH.
I (Rolf) don't support legacy BetterTelnet in any way at this time. The only reason you would want to use it is that it uses somewhat less memory than MacSSH when a lot of scrollback lines are stored. You can work around this issue in MacSSH by turning off "Store attributes in scrollback" in the terminal settings. However, for historical interest, the BetterTelnet downloads are below.

Five Things I Learned
Application was written by Rolf Braun and compiled using CodeWarrior Gold version 10.
MacSSH is based off BetterTelnet it brought much-needed SSH tools for Mac OS Classic users.
According to Rolf Braun's official website, the final version is BetterTelnet 2.0fc1, FAT (68k and PPC combined binary). This is weird because the screen shot I have shows it version 3.0 Fat ( 3 Jan 1999)
When I was using BetterTelnet frequently, I created settings files that I would use to launch BetterTelnet with my predefined keys and telnet location.
If you want to fix a bug or add a feature to BetterTelnet - you can! You can download the source code and compile the software.
