Serial port in C++ on BeagleBone Black

[RobertCNelson]

Hi @taek8461,

@taek8461

I wanted to use /dev/ttyO0 and another serial port.
I think /dev/ttyO0 is serial terminal port.

/dev/ttyO0 is a symlink of the real node: /dev/ttyS0

@taek8461

then when a key is entered in the serial terminal,
the entered key does not appear in the terminal.
when I pressed ‘Enter’ key, prompt was appeared without line breaks.
Why is this happening?

Correct, this is a legacy and default response for Serial Communication. If you want the ‘Enter’ Key to appear how current application respond to it, you’ll need to send a “Carriage Return” and “Line Feed” instead.
