Thanks Thunder, will streamline the code as you suggested. On the syncs, i repeat all the commands until i get the expected success code as passed in as the second parameter sent to sub SendCommand. I need to limit the number of retries but figure that will be a later addition, also will be adding something to power cycle the camera if i get to 60 with no success. Here is the config file, wondering if the handshake part is failing, i have tried RTS, XOFF, DTR and none they dont seem to make a difference. I have no experience with this level of serial so thanks for taking a look.
