1435 Packet Exchange (PEX or PE) and, like SPP, is layered on top
1436 of IDP.  PEX is important for a number of things: Courier
1438 of PEX, and many Xerox servers are located by doing a PEX
1440 implementation of PEX in the kernel,
1442 and the use of one peculiar \fIgetsockopt\fP.  A PEX packet
1450 struct pex {
1452 	u_short	ph_id[2];	/* unique transaction ID for pex */
1453 	u_short	ph_client;	/* client type field for pex */
1458 field indicates the PEX client type (similar to the packet
1459 type field in the IDP header).  PEX reliability stems from the
1468 that no response will ever be received.  To simulate PEX, one
1485 simulate PEX fully is left as an exercise for the reader.
