On the off chance Wasp support would tell me, I called to ask for the CRC16 polynomial and method used on the Wasp WDT2200. They wouldn't tell me.

However, if anyone wishes to use different filenames for their own application, I will use an analyzer to record the CRC16 bytes needed for the download command (Scanner to Computer) for such filenames, as I have time of course. Since Serial communications are extremely reliable, and since...
