I enable ttyO1 - ttyO5.
I try to send and receive, but no success.
echo "Hello" > /dev/ttyO1
With another Terminal I start before:
sending seems ok, now error.
receiving is waiting and waiting…
I close Pin 24 and 26 on P9 (TX to RX)
So, normaly I should receive on the same Port what I send, right?
Can someone help? Thank you!
