Hi all! I have a little problem. I have to make an RS 485 connection with an Arduino mega. Could you help me how can I get a Clear to Send (CTS) and a Ready To Send (RTS) signal from the panel? How can I write the program for it? It's almost the same like the RS 232? Thank you!

The RS485 standard does not use CTS/RTS. Those are RS232 signals.

More information would be helpful.
