File descriptors cannot be passed between nodes in a TSP-Link
®
system, so the io.open(),
fileVar::read(), and fileVar::write commands are not accessible to the TSP-Link system.
However, the default input and output files mentioned above allow for the execution of many file I/O
operations without any reference to a file descriptor.

fileVar:flush() (on page 11-242)
