Class 1 ” Dedicated connection service.
- Acknowledged delivery
Class 2 ” Multiplexed service.
Class 3 ” Datagram service. This is the current class of service provided for by Hewlett-Packard. The device drivers determine if data is not received and needs to be retransmitted.

Other classes of service may follow. However, they are currently not defined.
