There several examples on using the serial ports with LabVIEW using serial
and VISA functions. Just search examples/IO interfaces/serial communication.
The examples are quite easy to use. The functions for talking to the parallel
port can be found in the Function Palette>>Advanced>>Port I/O. They are called
InPort and OutPort, they basically read/write to the data register of the
parallel port. The location of this register can be found in the Windows
device manager under lpt port resources.

error
"Capability not supported
VI 'untitled 2' was stopped at node 0x1D8 of subVI 'In Port.vi'"
