Step 1 is /onQueue and this will come back immediately when SPJS has taken your command and queued it to memory/disk. Step 2 is /onWrite when SPJS actually has written your command to the serial device. If the device takes a while to execute the command it could be a bit of time until that command is physically executed. Step 3 is /onComplete which is SPJS attempting to watch for a response from the serial device to determine that indeed your command is executed. Please note /onComplete can come back prior to /onWrite based on your serial device and how fast it may have executed your serial command.</p> <p>You can omit the Id if you do not care about tracking. You will get callbacks with an empty Id so you will not be able to match them up.
