Is it a problem with the underlying driver? nigelwright7557 Member Joined 2008 murtonpikesystems.co.uk 2019-12-05 2:27 pm #2 2019-12-05 2:27 pm #2 Quite often with data packet based systems they add CRC and length words. You need to look up spec and see what is expected. You must log in or register to reply here.
