TCP/IP Communication

Read and write data over TCP/IP interface

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.

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.
