Node-red Serial not showing data, but can see in putty or moserial

HI all,
found an interesting issue (possibly), my friend purchased some Atlas Scientific modules and i was setting up a datalogger for him, but i couldnt get any data from the units over serial, this was remote so had plenty of video chats with him wiring them up and me checking. They're are connected to ftdi boards for now just to check if they worked.
Anyway he dropped the units round and i tried his pi out, with serial and debug node. Check Baudrate parity etc. Nothing, it said connected but no data.
So i tried putty, no rewiring or any changes to kit and bang Data flow.
I then connected to my laptop with ubuntu 20.04 ran node red re did the serial and debug node. Nothing, so tried putty , data fine, tried mosserial data fine.
I have just finished doing some code with GPS and world maps, so i know the serial node works fine.

any ideas please

How did you setup the rest of the Serial node?
I'm curious what you set for the input settings.

DOH, my bad, i had the split input set to \n, which isnt sent by the unit. i thought it would have just sent a long string, but i suppose the buffer is waiting to find the char to release it.
Thanks for the question, made me look again.
