Thanks Brian,

The manual that I read said to set these variables to "any non-blank" 
character, I was setting them to "1" and it was not working. After 
setting them to "Y" I can pick up an escape. I will see if I can find 
the discussion to the screenio.c tweak. Do you perhaps have a pointer to it?
