Thanks for the reply.
I am simulating TCP client and TCP server with 2 Node RED instances.
TCP Client:
[{"id":"f4ef0b95.8d83b8","type":"inject","z":"3b9021bc.3cd74e","name":"Node RED 01","props":[{"p":"payload"}],"repeat":"60","crontab":"","once":false,"onceDelay":0.1,"topic":"","payload":"000000000000008c08010000013feb55ff74000f0ea850209a6900009400d6120000001e09010002000300040016014703f0001504c8000c0900730a00460b00501300464306d7440000b5000bb60007422e9f180000cd0386ce000107c700000000f10000601a46000001344800000bb84900000bb84a00000bb84c00000000024e0000000000000000cf00000000000000000100003fca","payloadType":"str","x":380,"y":100,"wires":[["43bf8d1a.3dc1d4"]]},{"id":"43bf8d1a.3dc1d4","type":"function","z":"3b9021bc.3cd74e","name":"","func":"\nreturn msg;","outputs":1,"noerr":0,"initialize":"","finalize":"","x":503,"y":100,"wires":[["84e19867.dda908"]],"l":false},{"id":"84e19867.dda908","type":"tcp out","z":"3b9021bc.3cd74e","host":"10.23.50.3","port":"1001","beserver":"client","base64":false,"end":false,"name":"","x":660,"y":100,"wires":[]}]
TCP Server:

I am trying to send Reply to TCP client from TCP Server. Is there any possibility to read the server response at TCP client instance?
