<div>If I'm reading drivers/blazer_usb.c correctly, "UPS No Ack" causes the read loop to retry (up to 10 times). This is similar to the USB-to-serial converter code in tripplite_usb.c, where it looks to make sure that the received buffer differs from what was sent the last time. But it's possible that this UPS doesn't use Q, just Q1 (string index 3, which does return a somewhat normal-looking buffer).</div>
