SampleResult fields:
ContentType:
DataEncoding: windows-1252

Steps followed:

1. Set up TCP in JMeter properties:

• tcp.handler=TCPClientImpl
• eolByte = 111
• tcp.eolByte=1000
• tcp.charset=
• tcp.status.prefix=Status=
• tcp.status.suffix=.
• tcp.binarylength.prefix.length=2

2. TCP Sampler Config

• TCPClient classname=TCPClientImpl
• Servername=xxxxxx
• Port: 3432
• Timeouts: Connect(2000ms,)Response: 2000ms
• Reuse Connection -enabled

3. JSR223 Sampler
   Payload Request :

def payload = "UNB+IATA:1+1S+XX+121103+FF168019110033++ETK1+O'\n" +
"UNH+1+TKCREQ:00:1:IA'\n" +
"MSG+:131'\n" +
"ORG+1S+99999999:X7HH+VZX++T+GR+CXN'\n" +
"TKT+676713121:T'\n" +
"UNT+5+1'\n" +
"UNZ+1+FF168019110033'

If this code:

def payload = "UNB+IATA:1+1S+XX+121103+FF168019110033++ETK1+O'\n" +
"UNH+1+TKCREQ:00:1:IA'\n" +
"MSG+:131'\n" +
"ORG+1S+99999999:X7HH+VZX++T+GR+CXN'\n" +
"TKT+676713121:T'\n" +
"UNT+5+1'\n" +
"UNZ+1+FF168019110033"

is the complete code for the JSR223 Sampler - it does absolutely nothing.

If you want to send it over TCP you need to put the payload into "Text to send" field of the TCP Sampler:

If you want to send the "payload" using JSR223 Sampler you need to add the relevant code to do it, the simplest one is:

def payload = "UNB+IATA:1+1S+XX+121103+FF168019110033++ETK1+O'\n" +
        "UNH+1+TKCREQ:00:1:IA'\n" +
        "MSG+:131'\n" +
        "ORG+1S+99999999:X7HH+VZX++T+GR+CXN'\n" +
        "TKT+676713121:T'\n" +
        "UNT+5+1'\n" +
        "UNZ+1+FF168019110033"

def socket = new Socket('xxxxxx', 3432)

socket.withStreams { input, output ->
    log.info(input.newReader().readLine())
    output << payload
}

The output will go to jmeter.log file.
