The driver already sends the writes regardless of EXECUTE_ON_WRITE. I'll correct the commit message and add the blank line. I also missed the restriction on write-triggered CH_VALUE events. Reporting VOLATILE needs corresponding changes to the event handling. I'll check the write-notification paths, including asynchronous completion, and test those changes before sending v5. Thanks, Michael
