How Does Terminal Emulation Effect Telnet?
It’s important to understand terminal emulation. Back in the days when UNIX gurus sat in Ivory Towers, users connected to Unix machines using equipment called “terminals”. Terminals are still used by many companies today (even us), but have in most cases been replaced with PCs running software programs that appear to the Unix box to be a particular piece of hardware (like a DEC VT100). Because there are many different types of terminals out there, your Telnet software has to act just like (or emulate) the real terminals that are connected to the host computer you wish to access. Each Telnet program (or client) allows you to specify the type of terminal to use before you connect. It’s usually best to try VT100 emulation, but if the screen looks jumbled or keys will not function properly, try ANSI.
