Read the standard input with the Read instruction:

Public Application_Read()

  Dim Keys As String

  ' Read up to (so the negative sign) 256 characters from the standard input
  Keys = Read -256
  ...

End

If you don't read the standard input, the Application_Read will be called 
again and again, as there is always something to read!

Read (again?) the mail I wrote about a component based on the ncurses library. 
Only that library has all the features to deal with terminal output and "real-
time" terminal input.

And I suggest you read all documentation you find on Linux/Unix terminal 
management, and look at the "stty" shell command.
