With this tutorial you should be able to get Telemate 4.2x (or likely any DOS terminal program if you prefer Telix or Procomm Plus) running under WinXP/Vista/7 x86/x64 and OS X Lion (likely any Intel Mac OS, 32 or 64 bit) while operating as a telnet client.

It runs rock solid stable, even stable enough to script. I've been running Telemate Tele-Arena scripts for nearly 2 days straight without issue. So if you've got old DOS terminal program scripts for your favorite games, you're in luck!
