I have just connected up the new version of Stdiodemo which allows spreading connections over more than a single port.
It works fine and obeys the u q & l commands when sent from my computer keyboard.
As an example when I send
l the_message [enter]
I see on the display
However I have gone a step further and connected another AVR by cross coupling the rx tx pins.
The intention being to send messages from that rather than a computer.
My question is what exactly do I send?
does not work. All I get on the display is Hello_worlds and bye_byes.
The message is being sent continuously and I see it on the computer screen.
