[oopic] oSerialL - Really confused

I am trying to use the oSerialL to communicate with a another device,
but don't understand the results that I am getting. In doing dome
debugging, it seems that the value of the oSerialL object is all over
the place, even if it is not attached to anything. If I do something
like:

oSerialL MP3 = New oSerialL;

// Init Values

MP3.IOLineS = 31;
MP3.Baud = cv9600;

...

when I run this and open a dialog box, the value of the oSerialL
object constantly changes, even if nothing is attached to line 31.
What am I missing? If no data is being transmitted or received,
shouldn't the value of the object remain 0?

thanks
