Redo activates at the very end of the prolog and sends the redo_screen_mode and redo_line_mode sequences from the TDU to initialize the terminal in case it has downline loaded function keys or a keypad that must be activated. Check the TDU that you are using to see what sequences are specified to be sent. They must not be right for the Wyse 50. You can remove the enable_command_redo from the prolog to verify that this is the problem. -- Richard R.
