    Create a connection to a VISA resource. This example shows a connection to a device with the alias COM4 using the VISA-Serial interface.

    v = visadev("COM4");

    Set the terminator to "CR/LF" and write a string of ASCII data to the VISA resource v. The writeline function automatically appends the terminator to the data.
