The vbnbdgrm example demonstrates connectionless (datagram) com-
munications using NetBios calls. The example can run as a sender 
or as a receiver.

To run as a receiver:
1. Specify the local Netbios name: Rcvr
2. Specify the role as Receiver (default)
3. Click "Recv" Button. At this point, the app blocks until it 
   has received data from the sender. Otherwise you will need to 
   kill it with the task manager.

After the receiver is running, you can start run the app as the 
sender:
1. Specify the local Netbios name: Sndr
2. Specify the role as Sender, and specify Rcvr as the name to 
   send to.
3. Click the Send button. At this point, the app blocks until it 
   has completed the sends.

To run the example to send and receive broadcast, select Broadcast 
in the operation mode. 

The example also demonstrates using NCBASTAT to retrieve the MAC 
address on lana 0.
