How to use RS232 in that case?

Other Hardware General Electronics

Nice! But there is something i do not understand:

if i want to send something to the serial device, is there something like a handshake needed? I have no idea how to convert my serial.print() to "write.to.rs232"
So in short: is every RS232 device communicating the same way (besides the baudrate)? Or are there differences? If yes, how do i find that out?

Or is there a library i can use for that?

Thanks,

Pcace

PS.: btw, thanks for moving the topic to the right subforum!
