Hi David I am confused about what you are doing at this point. I am not sure what you are referring to when you say you don't see any response on the screen from the "original sketch." Do you mean the simple serial echo I posted above? If so, exactly what do you see on the serial monitor screen?
The sketch you attached to your last post appears to be part of the serial echo sketch pasted into the TMCC snippets sketch. It's hard for me to know what's going on if you're mixing them together like that....
It also appears your Arduino software is fairly old (looks like 1.8.3). It can't hurt to update to the latest release (1.8.15).
I thought I copied the sketch (the one in my previous response) directly from what you sent a few days back. Yes I am trying to run the simple serial echo test where I send a command (any command) from the hand-held controller and hopefully something appears on my computer screen. I posted what my screen looks like and when I push a command button on the hand-held nothing changes on the computer screen. I have downloaded the latest Arduino software. Could you please resend me the entire sketch that I need at this point to see if I can establish communications between the Arduino and the Legacy controller?
