Hi,

and welcome!  I think the library Keyboard should do what you want.
This exports KeyPressed and Read - the KeyPressed returns TRUE if
the Read will not block - so you can construct a loop to consume
outstanding characters, rather like this:

   WHILE KeyPressed() DO
      Read(ch)
   END ;
   (* at this point all outstanding characters are consumed *)
