TCP/IP Communication
Transmission Control Protocol (TCP) is a transport protocol layered on top of the Internet Protocol (IP) and is one of the most used networking protocols. MATLAB® support for TCP/IP client communication enables you to use network socket communication to connect to remote hosts from MATLAB for reading and writing both binary and ASCII data.
Use tcpclient to
create a TCP/IP client that connects to a server or hardware and perform read and write
operations.

Topics
- TCP/IP Communication Overview
Use network socket communication to connect to remote hosts from MATLAB for reading and writing data over TCP/IP.
- Create TCP/IP Client and Configure Settings
Connect to remote hosts or hardware from MATLAB for reading and writing data over TCP/IP.
- Use Callbacks for TCP/IP Communication
Enhance TCP/IP communication by executing a callback function when a specified event occurs.
- Write and Read Data over TCP/IP Interface
Write and read data to and from the remote host connected to the
tcpclientobject. - Configure Connection in TCP/IP Explorer

Featured Examples
Communicate Binary and ASCII Data to an Echo Server Using TCP/IP
Set up an echo server and communicate with it using TCP/IP by creating a tcpclient object. Binary data and terminated string data are sent to the server and the server echoes the same data back to the client.
