The instrument grammar gives the option to add a carriage return and line feed to the end of a data stream. Enable this option in the instrument, then utilize the CRLF mode in the “TCP read” block. WebFor TCP READ, you have to provide the CONNECTION ID (obtained from TCP OPEN CONNECTION ), a MODE (more about that later), and a NUMBER OF BYTES TO READ (more about that later). When you’re done, call TCP CLOSE CONNECTION. For the server side, it’s only a tad more complicated: Call TCP CREATE LISTENER. This gives you a LISTENER ID. most hit bridges uk
