I have search far and wide and every where i see people asking a similar question and the people answering the fail to understand the problem.
I have an inject node that must write msg.payload="Hello World" when pressed.
I have a debug node that display msg.payload.
I have putty that can make a TCP connection to node red.
lets choose a TCP port 7000 for this example
please set up node red so that PUTTY can connect to TCP Port 7000
then Wire the inject node to the TCP connection so that when I press the Inject, the text appear in PUTTY over the TCP Connection Port 7000 AND wire the debug node to the TCP connection so that when I typed text in PUTTY it will appear in the debug node in node red
Can someone please show me how?
