Most serial instruments require one. Often it's the carriage return constant but it could be something else, your instrument's documentation should tell you what to use. Find the constants on the string palette. Also, you might want to use VISA instead of the old serial drivers. If you plan to upgrade to LabVIEW 7, you'll find that the old drivers don't exist.
