Acquiring through the mircophone

[Gorelick]

In previous support I was told to use port 0 to initialize the
microphone port which worked on the test exe I used to sample the
waveform.  I did not have access to the block diagram and cannot
figure out how to record from port 0.  I have played around in the
instrument IO dialogue but I only see settings for LPT 1, COM 1, COM2
etc.  Is there an easy way to simply acquire this signal??  If anyone
has a simple VI which has an example of this it would be greatly
appreciated!
