I have a few scanner questions that don’t appear to be covered in any documentation I can find:
 

XML command string to turn off/on the successful scan beep. Documentation only shows how to use a custom wav.
XML command string to change the successful scan beep. Documentation shows only how to send a beep, not change the scan beep.
XML command string to vibrate handle in silent mode or to turn on silent mode (does DS4308 have this option?)
Comprehensive list of commands supported by DS4308!

 
Thanks.
