\n ( new line) means look for the carriage return and line feed characters, together. .? ?Char(13) Char(10)

A break through of sorts late this afternoon

In the port setup is a group of boxes under INPUT.
The second row down is a line? SPLIT INPUT with two boxes which default
to [On the character]and [\n]

Changing the [\n] to "A"? ( one of the characters in the serial string
we are looking for) allowed information to start coming out of the
serial port into the rest of the flow.

??I am sure that "A" is not likely correct it certainly screws up the
serial message parsing for the later logic to act on
But it points as to where to start looking further ....... Is "\n"
supposed to be a number or \(number)? maybe?

Can anyone point me to a complete set of DOCUMENTATION? that defines
what all the choices under INPUT are and how to choose appropriately?

Dave WO2X and Alan thanks again for all your suggestions earlier. Dave a
video call tomorrow at this point is not necessary. Pointers to real
documentation if it exists appreciated though. Until that surfaces I
will likely play the "monkey at the typewriter" till I figure out what
goes in all those boxes and why.

Tomorrow I will point the output of the Serial node to Msg-Payload in
DEBUG mode and see what the data string really looks like
