Sorry, I just have to smile here... :-)

Okay, your problem is a well known "feature". The answer is: The VT220
don't have an ESC key.

When you are using the terminal in VT52 or VT100 mode, it uses F11 as ESC,
because the VT52 and VT100 has one, and it's supposed to emulate those.
However, in VT220 mode the F11 key sends a complete escape sequence
identifying it as F11.

The one solution I can give you is that you will get an ESC by pressing
