  34 This example shows how to use the PDU bundling features in KDIS.
  35 If you are sending multiple PDU in a short time then bundling
  36 them into a single datagram can help reduce bandwidth and increase performance.
  37 Note: Not all systems support bundling.
  38
  39 Run the PDU_Factory2 example to see the output of this example, PDU_Factory1 does not support bundling.
