What is a TCP listener?
TCP provides reliable communication between a client and a server. The TCP Listener component enables iBOLT to listen continuously for requests made by a TCP client on a TCP port. The component then triggers an integration flow when it detects a specific request from the TCP client.

Using TCP Services. The TcpClient class requests data from an Internet resource using TCP. The methods and properties of TcpClient abstract the details for creating a Socket for requesting and receiving data using TCP.
How to request data from an internet resource using TCP?
The TcpClient class requests data from an Internet resource using TCP. The methods and properties of TcpClient abstract the details for creating a Socket for requesting and receiving data using TCP. Because the connection to the remote device is represented as a stream, data can be read and written with .NET Framework stream-handling techniques.
