JSI Tip 3760. How do I cause a batch file to beep for attention?

To cause a batch file to beep for attention, you need to send a BEL character.

The easies way to do this is to open a CMD prompt and CD to a folder in your path. Then type:

edit bell.bat@echo           (Saves bell.bat)           (Exits edit)

NOTE: <> indicates that you type the key(s) within the <>.
