Re^2: Serial camera - Issues connecting

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.

OK, after pulling my hair out on this i tried simply sending 30 sync commands in a row, one pack command with 30 iterations all at once then started the normal sync and other commands. This worked! Purely a guess that it took many characters for the serial port and cam to sync baud?? but its working. The confusing part was that after the first couple of syncs i would get an ACK but then subsequent commands, like set picture size, would never get a response. Thunder, the shortcut to find the frame num with hex worked great, removing the leading 0x's did not, complained at runtime. Appreciate you looking at this for me.	[reply]
