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

Toubib has asked for the wisdom of the Perl Monks concerning the following question:

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?
