Accessing parallel port in VB

Sir,
I am sathesh working in an educational institution in Singapore and doing a project on Navigational Systems which is a 3d virtual reality project. In this we have several signals coming into the computer system and wish to distinguish them. A serial communication program with MSComm control can take and distinguish one signal at a time. Is there a possibility to use the parallel port and communicate with it using a vb program. If yes, please suggest me a technique to do so.

Thanks and Regards
Sathesh

get one of those port dlls (search the net for inp and out)
