How do I emulate a VT100 terminal to interact with a remote GUI

[Toubib]

I need to interface with a vt100 GUI on a remote system. When I log in, my "shell" is a vt100 GUI. All I need to do is send some keys to it but for that I need to emulate some kind of VT100 terminal through my socket. Does someone have an idea how to do that?

See Expect. The Expect programming language (and the perl Expect module that provides that functionality to Perl users) are designed percisely for doing what you want: interacting with console and command-line processes like it was a user at a keyboard.
