Term::VT102

The Term::VT102 Perl module provides emulation of a VT102 terminal.

Like the `expect' Tcl extension, this module is intended primarily for use as a way of automating processes; for instance, you can write a script which connects via telnet to a full-screen service of some kind (such as a router, or a telephone switch), uses this module to parse the output, and therefore can tell what is currently "on the screen" and react accordingly. `expect' cannot really do this, as it is stream-oriented, rather than being able to tell you, say, what's on the top row of the screen.

You can download the latest version from here or from your nearest CPAN mirror.
