Hello,

I am using DS2278 with RS-232 interface connected to a Linux machine. I am wodering, if there si some simple way to confirm the reception of the data sent by the DS reader to computer port - for example to send some command from PC to reader and it will beep 3 times or something like that, so I can inform the operator, that the code was sucesfully recieved by the computer.

I am using Node-Red enviroment, so some code in Javascript would help. Thanks.
