TCP send and receive

[shlee11]

I am writing two programs(server, client). They communicates though TCP.

[Operation]

1. Client sends "ABC" to server.

2. Server receive "ABC" from client

3. If server received "ABC", server sends "DEF"

4. Client receive "DEF"

1 and 2 operation work fine. But 3 ~ 4 don't work.

I followed this guide(https://www.ni.com/ko-kr/support/documentation/supplemental/06/basic-tcp-ip-communication-in-labview...)

client.vi

-> 

server.vi

->
