Indeed it is not a terminal.
AFAIK it's a pseudoterminal based upon a TMemo or TSynEdit (too lazy
to look it up).
The code is in $(LazarusDir)/debugger/pseudoterminaldlg.pp

There is a bugreport already about it's behaviour (echoing control
characters) in http://bugs.freepascal.org/view.php?id=22349

Feel free to post enhencements.
