Hello,
enclosed there is an application note which shows how to work with the
serial port.

You also can use the serial read function or VISA read function to read 
the parallel port. But before you have to set a porrt no. for your LPT 
in the labview.ini to access to the LPT. This is documentated somewhere 
on ni.com.

How can I display a TTL-Signal immpressed at a parallel port?

[wimmer franz]

I get a real TTL-Signal from a resolver which is connected at the
parallel port. From this parallel port I would like to read the
frequency of the signal coming in. The resolver is connected at the
parallel port at only one data pin and at a ground pin, without using
a DAQ. (In past I used the InPort- Box of a example in developer zone,
but it didn't work, because of the C-code)
