Richard “fixed the start-of-packet detection and straightened out the indexing in serialPort_DataReceived“.
The serial driver (or the mindflex, or something…) is stopping the flow of data after a few seconds of operation so I can only test a few seconds at a time until I’ve cleared that up. Disabling/enabling the com port in device manager fixes it up temporarily, which to me indicates a driver issue, rather than a problem caused by anything the mindflex is doing.
