KiTTY is Win32-native PuTTY
On the other hand, if you're wondering what PuTTY is, let me tell you! It's what I'm here for, after all. PuTTY is a free and open-source terminal emulator; you can use it as a client for Telnet, SSH, raw TCP sessions, and rlogin. If you have no idea what any of this means, I'm afraid KiTTY may prove less than useful for you.
I have used PuTTY itself on a Win32 system before and did not experience any problems. However, KiTTY is "made for" Windows, so in theory, it should run smoother and consume less resources (not that a terminal application is resource-hungry anyway).
So, the next time you read one of my posts about a surviving online BBS, and you find yourself wondering what application you should use to log on and find some new retro-loving friends -- KiTTY is the answer.
