Specify the terminator character
Description
For serial port., TCP/IP, UDP, and VISA-serial objects, you can configure Terminator to an integer value ranging from 0 to 127, to the equivalent ASCII character, or to empty (''). For example, to configure Terminator to a carriage return, you specify the value to be CR or 13. To configure Terminator to a line feed, you specify the value to be LF or 10. For serial port objects, you can also set Terminator to CR/LF or LF/CR. If Terminator is CR/LF, the terminator is a carriage return followed by a line feed. If Terminator is LF/CR, the terminator is a line feed followed by a carriage return. Note that there are no integer equivalents for these two values.
Additionally, you can set Terminator to a 1-by-2 cell array. The first element of the cell is the read terminator and the second element of the cell array is the write terminator.
When performing a write operation using the fprintf function, all occurrences of \n are replaced with the Terminator value. Note that %s\n is the default format for fprintf. A read operation with fgetl, fgets, or fscanf completes when the Terminator value is read. The terminator is ignored for binary operations.
You can also use the terminator to generate a bytes-available event when the BytesAvailableFcnMode is set to terminator.

Values
An integer value ranging from 0 to 127, the equivalent ASCII character, or empty (''). For serial port objects, CR/LF and LF/CR are also accepted values. You specify different read and write terminators as a 1-by-2 cell array.
