That's Term::VT102, right?

An Expect object is just a file handle that you can read from and write 
to, so it should be easy to link that to Term::VT102, just read a chunk 
and call process() with it.  The OUTPUT callback should simply do a 
syswrite to the Expect object.

No, you can't use the expect() method concurrently, as this would 
consume the characters.  Instead, you have to register a ROWCHANGE 
callback and do your processing there via normal regexp matches.

[BTW, what I think is missing from Term::VT102 is the ability to get a 
callback when the cursor position enters certain coordinates (to be 
able to react to a prompt).]

Hope this helps,
