David, Hi. I believe your starting point will be the "Communication" section of the docs. For the latest v17.3 this is the link: https://doc.4d.com/4Dv17/4D/17.2/Communications.201-4385988.en.html

I need to send command codes to the device and then receive data back from the device. Does anyone have experience with this? Ideally, some help in finding some technical documentation on how to do this would be ideal. Thank you, -- Regards, David Loeppky ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
